What a wonderful video.... no body taught me like this when i was a student... I am now a doctor and reside in Dhaka, Bangladesh.... but i watch maths video to recommend to my son (who is now in year 8) and also to learn myself. I showed this video to my son..... he liked it so much! Thank you Jane, You are great.
Hello Dr. Jamil, enjoyed your comment. Thank you for writing. For some of us, it is always fun to look at math. Glad your son is motivated, and hope he does well. Best, Jane
Update May 2023, responded to a comment today and discovered that I had not replied to many comments (lack of time). Thanks to those who wrote 9 or more years ago. Hope all of you did well and have careers that you enjoy.
in layman terms, a function assigns to each input value, a unique output. as you saw, a trig function assigns a number to each angular measure. there are other functions that have to do with triangles, such as inverse functions. functions are useful. without functions there will be no advanced math. you can read more on wikipedia. math is FUN :)
I burst into tears finding this video of yours, Ms. Jane. I wish I could've attended your class in high school and college. Math and calculus exams still remain so regular in my nightmares. Thank you for your both math and piano tutorials, enjoyed and learned. The cheat sheet in the final is a gem.
Oh Ruixiong, so glad you found this trig lesson and it helped. Take your time to learn, understand everything before moving on, then you will enjoy math and do GREAT! Be happy 😊
Hi Jane. I found this Trig lesson fun as I'm 63 years old and brings back memories. I remember writing all the formulas down and using a slide rule to build the answer. Calculators make it too easy in my opinion. I actually found you on TH-cam because I bought a Yamaha Digital piano and starting learning. Thanks for all the vids. Math is fun.
raykrv6a Nice to hear from you. People our age were fortunate to learn trig before that SAHCAHTOA mnemonic became the *standard* way of introducing trig. Mnemonics promote memorization with zero understanding. There goes all the fun! Teachers, especially math teachers, must avoid using mnemonics. Congratulations on your new piano and new hobby. It is a wonderful one. Hope you started with my sight-reading lessons.
no need to be sorry, just rewind and review until you understand all of it. this is a very important basic lesson. you need to understand every bit of it to do well in math later.
Jane, Thank you so much for refreshing my memories from the school after almost 20 years. I really enjoyed listening to your lecture. I just felt as If I were a young student and was sitting in the class. Please keep up the good work. I would love to check out your website, too. Once again, Awesome Job. I loved it.
+raminak love nice to hear from you. glad you find enjoyment revisiting trig. it is amazing how a simple idea as taking ratios of sides would lead to vast applications.
This is an awesome tutorial because it teaches the basics in a simple, yet gentle, format within a few minutes that anyone can understand! Everybody can't teach, this video proves that Jane can!!!!! Kudos :)
i could never figure out when to use cos or sin and this is the only video that CLEEEEAAAAARLLLLYYYYYYYYY EXPLains it...thank you for being very detailed...
Nice job explaining everything. You spoke nice and slow so the information had time to process in my rather small brain. I learned more in lesson one and two than I did in four years of high school. Some people speak geek and like to speed thru everything to show how smart they are but they are poor teachers. Again nice job people loke me appreciate it. Thank You
I totally love your video, brought back memories, unfortunately I didn't get as good an explanation as you did now back in the day, but I have the privilege of passing your video on to my kids. Thanks!!!
easiest way is to use my website. there is a "math tutorials" page that lists the ones I've done. log and exp belong in precalc. I'll get to those someday, perhaps sooner because you asked.
Thank you for this. I was about to jump back into trig as a non traditional student and was feeling a bit anxious about starting math again. This seemed to put me a bit at ease.
I was always confused with flat triangle and the values of Sine0 and Cos0 as to their values. Now at the age of 54 I have cleared it. thank you very much.
Thanks for writing, Mohamed. Glad you got the idea. Later in calculus, the sine and cosine of any value are defined via the unit circle. For any point on the unit circle, the sine value is the y-coordinate, and the cosine value is the x-coordinate. Lesson 2 hints of that concept.
+Jane I adore Piano... I'm not pro unfortunately... my Branch is maths and I adore Maths but I'm not very good at it unfortunately...But you, you can help people by tutorials and lessons. I just find my perfect personality on you May god bless you're the most amazing human I've seen in my life hahaha
Thank you for this video, I'm trying to familiarize myself with Trigonometry before taking it during the short winter session since my work prevented me from taking it in Fall, I've looked at other videos and the slow instruction really helped the information "sink in", (pausing the video helped too) Much appreciated!
If your background is strong, i.e., if you really know your algebra, geometry, and pre-calculus, you’re going to do well in college calculus. You don’t need a high school calculus course. The above was the conclusion of a long-term Harvard research study, published July 2018. It's upsetting and incredible that something so obvious was ignored for the last 50+ years.
I been working on your Trigonometry demo today Jane, and though seemingly easy to follow, from looking at your tabe I got to brush up on my fraction devisions. I wrote it all down as well as you mentioned in another video to do. It does help. I also used my casio scientific calculator fx-82A to find square root. (I bought it back in 1988 and still battery is not run out and is working perfectly.
@Rachel Rose Estrebilla Google+ will not allow me to REPLY to your comment. The sohcahtoh scheme is terrible. Forget about that completely. Then watch this lesson from the beginning. Pause and rewind when you do not understand anything. The definition of tangent as sine/cosine is most important. When the triangle sides are used, it comes out as adjacent/opposite.
@MrPianist101 one lesson will not be of much help because algebra encompasses many topics. I did one on factoring that you might find useful in Algebra II. The best thing you can do is get a Barron Algebra thick workbook (library) and do as many problems as you can. my husband and I are seriously considering starting a math series, but you will be way ahead of us by then. good luck. algebra is fun, and it is an important foundation for calculus. you can message me questions any time.
love part one of your trig.video i learned what I couldn't learn back in high school in the 70's. Thank You; Now is it possible that you could upload a part two of trig? and maybe if you could add ratio proportions,percents,fractions,basic shape measurements and how to an essay? Thank You: Billy
I love Trigonometry :) I studied it alone years ago... And found it simply amazing !!! Good job as usual !!! I think that I'll follow your courses just because you speak slowly, and that will help me to master the mathematics vocabulary and syntax in English :)
I missed out on learning about this stuff in High School . . But am wanting to, now that I'm older and there is more time to focus in and concentrate.
why was this in algebra? trig is fun and easy. get a good work book, study one section at a time and do the problems. if you have questions, send them to me and I'll help you.
i was a bit confused on the reciprocals, but when i solved the homework i realized that the reciprocals is nothing more than just switching the numbers. awesome instructional! learned alot!
Are you taking trig? Do you have a book with homework problems? Now that you have a good idea what is going on, the other YT lessons with examples should work for you. if you find a particular problem that you cannot solve. write back to me. okay?
im taking notes! got a booklet labeled with each lesson. i did 1-6 and then i watched the videos again to review the notes. made alot of progress, and the way you explain it is superb.
To all, I started to edit the automatically generated YT closed caption today. What a mess they made of it. It'll take me a few days to finish. Those who requested subtitles in Portuguese will be able to use the translation feature.
Hey, I like how this is well explained and made. It had really helped me, but in my opinion I wouldn't just say "duh" in the middle of a lesson/ learning experience. No matter how fundamental you think the topic you speak about is, somebody in the world that is possibly watching your video right now could be offended. I'm not saying that this you tube video wasn't good, but just think about it. BTW I clicked thumbs up.
+Sydney Tucker thanks, but why is 'duh' an offending word? it means 'something obvious'. our niece taught us that word when she was a teen, now a prof :)
JANE SOS GENIAL EN TODO!!!! LASTIMA QUE NO INGLES!!!!! TARDO EN TRADUCIR PERO HOY ESCUCHE TU VOZ TAN DULCE COMO TUS MANOS EN EL TECLADO FELICITACION NO LO TOMES MAL OK YA SOY ABUELA DE 4 NIETOS Y SOLO SABE INGLES PEROLE GUSTA EL ROK, UN CARIÑO MUY GRANDE DESDE ROSARIO ARGENTINA BYE
please do not use vulgar language to comment under my videos, even if it is meant to be complimentary. if math is _____ in your country, you can learn on your own. khan academy covers almost every topic.
Good to hear from you. Best of luck on your entrance exam. If you are interested in how basic trig can be applied, see word problems. I recommend PatrickJMT.
Thank you, Jane. Many people learn best from hearing and seeing. Writing “flip it from end to end…” seems awkward; my bet is that virtually everybody would know what to do in this case. :I: Finkänslig
Yeahh! you've made a new math tutorial :) very good job Jane. you explain it very good. :) maybe you make some day a new channel with ONLY math tutorials ?! :) that's only a idea. your tutorials are very helpful. ;)
college alg is like alg 2 but with more information. it's also offered as a high school course just like trig. but i have to take them again in college since they werent worth college credit
Thanks :) , now to find a used textbook somewhere, that way I can start my "own curriculum" lol , these videos are helpful too, my friend took it in the ninth grade.
+Amil Abdullayev that was meant both as a joke and a _test_. most videos are watched less than 2 minutes. it took more than one year before some viewer commented on that flush! :)
Amanuel Amogne Thanks Amanuel. This is the simplest approach. That SILLY sohcahtoa mnemonic interferes with understanding the basic ideas! :( The next viewer question illustrates what I mean.
couple years back,i found this pointless to learn but it seams i'm going to need for the rest of my graphics design life. i wish my teacher would give real world example at beginning lesson so i don't get bored and only have to learn it for the exams, find out later like now that this is really important.
Jane is there a site on you tube where I can learn Trig from the beginning? I had Pre Algebra, Algebra 1 and 2, and College Algebra, a long time ago. Around the year 2000 in a community college. And I would like to learn trig from the beginning. Thank You.
I haven’t looked at trig lessons since I made mine. Have you checked? Avoid any who teaches by acronyms. Acronyms take away from understanding. Have you considered self-learning from a trig book?

What a wonderful video.... no body taught me like this when i was a student... I am now a doctor and reside in Dhaka, Bangladesh.... but i watch maths video to recommend to my son (who is now in year 8) and also to learn myself.
I showed this video to my son..... he liked it so much!
Thank you Jane, You are great.
Hello Dr. Jamil, enjoyed your comment. Thank you for writing. For some of us, it is always fun to look at math. Glad your son is motivated, and hope he does well. Best, Jane

Got busy doing other math topics. Might do more high school trig next because of your comment.
Jane,
Thank you so much for refreshing my memories from the school after almost 20 years. I really enjoyed listening to your lecture. I just felt as If I were a young student and was sitting in the class. Please keep up the good work. I would love to check out your website, too. Once again, Awesome Job. I loved it.

Everybody can't teach, this video proves that Jane can!!!!!
Kudos :)
+Etta Brown Thanks for your kind message, Etta:)
I'm confused. You teach Maths AND Piano??
+WooshaBaloo I'm always confused :) But math is my major, piano is my hobby
i could never figure out when to use cos or sin and this is the only video that CLEEEEAAAAARLLLLYYYYYYYYY EXPLains it...thank you for being very detailed...
THANKS!!!!!!!! Couldn't have passed my Trigo test without this vids
Nice job explaining everything. You spoke nice and slow so the information had time to process in my rather small brain. I learned more in lesson one and two than I did in four years of high school. Some people speak geek and like to speed thru everything to show how smart they are but they are poor teachers. Again nice job people loke me appreciate it. Thank You
Whoever came up with that 'sohcahtoa' acronym (memorizing without understanding) messed up several generations of math students.
I had not seen or heard this for 35 years. Thank you. And thank you for the sight reading lessons that I am now going to check out.
Have fun with the review! Hope the reading lessons are useful.
there are thousands of math topics, hard to choose from... will keep your suggestions in mind.

I belive You are proffesional teacher. You are also great speaker/announcer - helpful to learning english.
@Claybear17 the values come from the triangles in the examples
You're very welcome. Thanks for writing, and I hope you do well in your upcoming trig course.
lol, you are the first one who commented on my joke. I had thought my lesson went down the drain.
to distinguish among various concepts, such as angles and sides, or different coordinate systems.
not sure what college algebra consists of, because algebra i and II used to be in high school. this belongs in high school trig.
please do not confuse my students. this is high school trig. they have not learned about 'functions' yet.
meaning of the name of each trig ratio? please explain.
You're welcome Waldor. Glad it helped.
Thanks Jane, have an entrance exam next month for MBA. Knew nothing about trig, you helped me a lot. Cheers and keep up the good work. :)
Great, you must have earned your MBA by now 😊
love part one of your trig.video i learned what I couldn't learn back in high school in the 70's.

Daniel, surprised to find you here. Glad you are making use of these lessons. Enjoy...
Yes, they are great lessons, helping my English :)
how did you do? :)
I missed out on learning about this stuff in High School . . But am wanting to, now that I'm older and there is more time to focus in and concentrate.
you're very welcome. happy to hear the good news :)
why was this in algebra? trig is fun and easy. get a good work book, study one section at a time and do the problems. if you have questions, send them to me and I'll help you.
was that necessary?
most learn that as part of calculus. will add to list. all six functions?
i was a bit confused on the reciprocals, but when i solved the homework i realized that the reciprocals is nothing more than just switching the numbers. awesome instructional! learned alot!
good job, Denis! thanks for writing :)
Jane! more homework! im on lesson 6. went to your website looking for quizes but dident find any :/ can you add some? thanks :D
Are you taking trig? Do you have a book with homework problems? Now that you have a good idea what is going on, the other YT lessons with examples should work for you. if you find a particular problem that you cannot solve. write back to me. okay?
hmm....just realized you sped through lesson 1 to 6 in less than one day! make sure you understand every little detail before continuing
im taking notes! got a booklet labeled with each lesson. i did 1-6 and then i watched the videos again to review the notes. made alot of progress, and the way you explain it is superb.
@stevalianarbone amazing that the casio battery still works. i used to use a slide-rule! you probably never heard of those :)
To all, I started to edit the automatically generated YT closed caption today. What a mess they made of it. It'll take me a few days to finish. Those who requested subtitles in Portuguese will be able to use the translation feature.
Thank you mam
@Banvoolivre your request for a piano tutorial does not belong here :)
@Ishant Bibaan your comments do not have a reply option. extra work to reply :( can I ignore you from now on? :) my first language was not french
Excellent you are. Math & Piano, you've done well both. Thanks much Jane!!! 😍

Jane your video help me very much in trigonometry
Glad it helped, Vanita :)
you're welcome. glad it helps.

THANK YOU SO MUCH DEAR TEACHER. VERY USEFULLY.PRISE YOUR WORK.
hello @Ishant Bibaan, you're welcome :)
that is simple algebra. should be automatic like 1 + 1 before one learns trig.
Good to hear from you. Best of luck on your entrance exam. If you are interested in how basic trig can be applied, see word problems. I recommend PatrickJMT.
you're welcome
glad to know that :) keep at it and have fun. you're welcome to send me questions.
Thank you, Jane.
Many people learn best from hearing and seeing.

Thank you
Thanks a lot for this vid! I have a monster test on trig, and I think I'm gonna make it now. Thank you soooo much!
keep up the hard work!
the hypotenuse is always the longest leg. look at the picture.
Yeahh! you've made a new math tutorial :)
very good job Jane.
you explain it very good. :)
maybe you make some day a new channel with ONLY math tutorials ?! :) that's only a idea. your tutorials are very helpful. ;)
oh lord where do i find the second one i need more. every video i've seen so far stops here like this one and trigonometry is never spoken of again.
uploaded part 1 on sine function examples. part 2 will be on the cosine, and include changing periods.
college alg is like alg 2 but with more information. it's also offered as a high school course just like trig. but i have to take them again in college since they werent worth college credit
really really interesting.............I loved it ...it made me easy to learn and understand trignometry
thanks for your nice message, Venki !
can you make a video on graphing trig functions with shifts, amps, etc.?
Well thanks for this, today's lesson on our school ;) Trigonometric Functions. Really helps
You're welcome, my math lessons will help more than my piano lessons :)
Jane thanks
my english is not to good but I understand your video. thank you for showed this great video. help me very much. greetings from Mexico City
It was amazing..! Than a lot for the video... its the best video for the beginners in trigonometry..! May God bless you..!
arumbaka mamatha Shilohu thank you very much, arumbaka!
Loved ur video, helped me a lot.......
@paper900 mutation?
please review your square roots. those fractions are equal.
I always wondered how you will sound like ! Thank you so much ! youre such a talented person :)
glad to help. and thanks for the compliment :)
Thanks :) , now to find a used textbook somewhere, that way I can start my "own curriculum" lol , these videos are helpful too, my friend took it in the ninth grade.
finding a good trig textbook appears difficult. I've been searching the library without success.
I would like to ask the music song from beginning.Thanks a lot.

+Amil Abdullayev that was meant both as a joke and a _test_. most videos are watched less than 2 minutes. it took more than one year before some viewer commented on that flush! :)
+Jane Well I pity those who didn't survive up to the flush moment ;)
This is fantastic! Can you post more videos please.
It is a good video, it covers the main parts of Trigonometry.
Amanuel Amogne Thanks Amanuel. This is the simplest approach. That SILLY sohcahtoa mnemonic interferes with understanding the basic ideas! :( The next viewer question illustrates what I mean.
Many thanks from Ukraine, Jane!
I'm reacquainting myself to the maths in English and your videos are very helpful. Nice job!
Thanks for for your nice message, Johnnie. Have fun reviewing math!
sorry for my late reply. algebra is a pre-req for trig
Great explanation Jane
+Anish Nair Thanks, Anish!
@ 11:08: Learn the sin θ line; flip it for the cos θ line. Do tan θ = sin θ / cos θ for the last line. :I:
Finkanslig think I said that too. "flip it" sounds like a reciprocal though :)
thanks for writing, Yash :)
What was the music at the start of the video? It seems very familiar.
