Where modern textbooks lose rigor, the Organic Chemistry Tutor maintains it throughout all of his videos. This channel is a global treasure.
Why u paying him $30 a month for bro?? He probably already make bank off ads and views
@@BananaMan-qw2hj This man decided to be our mutual internet professor. He deserves everything he gets and more
Well good luck for me... i need to learn this by myself because of the corona virus
fucking same. i want to die
Not very difficult just keep practicing. AS level pure maths 1 paper questions are nice
Well now my teacher post lessons online and i still have my textbook with me for practice . So, i guess im in a better situation.
Kai Laine rip for students like us
Good luck, I feel bad, I have a choice to learn this but many people don’t, I do this for fun knowing it will probably save a lot of time in the future.
Nah this still don’t make sense
Thought I was the only one
i stggg
The you still probably watched it all is phenomenal progress! Hmu if you need anything.
@@FairleyWhite Hi😢
Real
I've learned more in this 14-minute video than I've learned in the past two weeks in class.
I’ve gotten worse
I was learning CAST diagram method in school
I learned how to do meth with organic chemistry lesson
Y’all get 2 weeks?
lol we went over this whole chapter in only one hour and a half
@@jaredr9469 nice big guy
how tf do people learn this
Update: I failed. Twice.
lane anderson exactly
lane anderson xD i feel you brother
😭
straight up fuck this shit
They give up on everything else and focus on it for 2 weeks or more. I missed the gym, work, all of it. But its worth it when you get an A.
mans saved me in physics and now in pre calc, what a LEGEND!
he saved you in physics and precalc. He saved me in precalc too. Wait... But hes an organic chemistry tutor!?!
@@aryathakur8014 he did have organic chemistry videos,so basically he"s got the whole package
@@aryathakur8014 Don't judge any book by cover and don't judge any youtube channel by name. His name is Th Organic Chemistry Tutor but he teaches maths, physics, biology and instead of my f*ck
Haha having to do this in calculus bcuz coronavirus=I have no clue how to do this, ni one taught me, and now I'm expected to know it like the back of my hand
@@aryathakur8014 he is a genius in anything maths and physics related
When I was studying in school, I think that I had missed some crucial explanations and I was clueless about how to solve such equations. I barely passed this topic, having memorized some basic formulas and writing them down. Today, at 28 years of age, I decided to look up what I had missed. It didn't even seem hard. Thank you for your work! I had struggled with what was written in the textbook for weeks, but with your video it took me only minutes. Awesome!
no offense but what are you learning this at 28 ?
I biggest regret in life is not finding this channel before I was halfway through grade 12
bruh same
I’m doing this topic and I’m in year 9
My biggest regret was failing my meth test in 3rd grade it mad me so sad
@@jjmaxman234 Shouldn't have done meth in elementary school bruh
Sir,Your workings and explanation is very detailed and easy to follow..Thank you very much for making this :D
THIS is the online school we need, and everybody wants.
Thank you! Literally that was everything I needed in a nutshell. Everything makes so much more sense now!
I learned more in the first 2 seconds of this video than I did in 70 years as a math professor
Underrated comment
MR. Organic Chemistry Tutor, thank you for a solid video/lecture on Solving Trigonometric Equations Using Identities. These are all classical Trigonometry equations from old mathematics.
Thanks for this!! Your videos are helping me like you have no idea!
Thanks again Mark Walberg
LOL
OMG !!! I was thinking the same thing lol
Mark who?
That was such a troll of a first question lol
I know right lmao
I still don't get it
@@user-ev9yz1yb7l nowhere on the curve does the function equal 0. Since sinx is the reciprocal of cscx, if sinx=0 cscx is undefined due to having 0 in denominator
I can never thank you enough how much enlightment this channel gave us
bro i always understood everything u said in your vids, but this one, for some reason, I can't understand shit from this lesson!
LMAOO SAME
trig equations are seriously the last straw, I cant do this no more dawg
THANK YOU SO MUCH!!! This was really helpful I finally understand it now.
Keep people with relevant videos, watch how to solve trigonometric equations, part 3 of 4 : th-cam.com/video/8I3-JqDFrRM/w-d-xo.html
Finals next week, these videos are priceless. Thank You OCT!
You and Brian mclogan are single handedly keeping my math grade above water
Keep people with relevant videos, watch how to solve trigonometric eqations, part 3 of 4 : th-cam.com/video/awJwzjZncp0/w-d-xo.html
Thanks! That last problem helped me with one of my problems. I never saw the quadratic formula, I only the book said that.....
hi thanks so much for these uploads. they are gonna save my day in june. am sure of that!
do we just need to know only these two triangles and a unit circle to solve all these questions?!
its not an "organic chemistry Tutor" video if he doesn't do that heavy cough
your videos really help me...BRAVO!!!!!
I failed precalculus. But I still want to know what this is. The universe is interesting
thank you very much for sharing your knowledge, it has helped me a lot
You are such a life saver. Thank you
the only channel to go to when you have math problems
facts!
I missed this lesson in precalc today because I was on a field trip and this actually saved me.
Thank you so much! My teacher isn't doing a good job at teaching this online and this is going to same me from failing my test!
After three hours of trying to get this topic, I was about to go mad because I couldn't understand. 4:02 into the video and everything is so clear. Thanks!
Thanks for this amazing video Chemistry Tutor 🖤
Thank u so much!!! Could u maybe do trigonometric inequalities?
You are a life saver imma champ the maths test i hv tomorrow
This was really helpful. Thank you! 💖
10 seconds in and I'm already lost..
Same
Looks like you need to repeat Grade 7 and learn your algebras then
@@glaciveestudios6170 it’s fine, I don’t use this in real life
@@glaciveestudios6170 hell ya i do, 7th grade math was a mess though, we had sub after sub and learned nothing most of the first semester. Algebra 1 9th we had too much fun, Algebra 2 11th we went too slow, I was destined to lose from the beginning
Not gonna lie, this channel has absolutely saved me in algebra 2. Thanks.
@ 2:45 the hypotenuse and legs for the 45,45,90 should switch values
My trig test tomorrow is going to cook me
yeah im failing tommorow
Lmao I got my exam today at 2. I’m cooked af
Aren’t the sides supposed to be 1, 1 and rad two on the 45,45 , 90 triangle?
Thanks very much for your explanation.
Very helpful for ib math hl review 👍🏼
Thank you you saved me for my test tomorrow
I'm glad I can help
@@TheOrganicChemistryTutorbro actually responds (6 years ago)
For the tanx=1, you are able to combine the two answers into pi/4+pi(k)
He has the amazing ability to make difficult things look much more easier
Another great video... Doing the lords work.
THANKYOU!
FOR EXISTING SIR!!!🥺 YOU'RE MY ONLY HOPE!😭💗I WISH I HAD YOU IRL.
Dude, I’m taking college trigonometry as a sophomore in High School and this class is killing me! These videos are helping so much! ❤
You saved my ass in chemistry last year and now you’re saving my ass in precalc lord bless you
YOU DESERVE THE WORLD
Great explanation for specific questions, but a deeper understanding of how to go about solving would have been more appreciated. I teach and tutor higher mathematics , I also look for vids to supplement my teachings with students. Some of your other vids are wonderful, my comment is strictly constructive criticism. Most of my students only need to understand how to solve the problem to complete their degree (and of course get the answer right). You would make a wonderful tutor if you haven’t tutored already. Cheers!
In my opinion this should only be supplemental to what is taught at school for the reasons you described.
Should we not add πn to tan for the coterminal angles since the period of tan and cot is π.
U re the best teacher bro jus make sure ur handwriting is good for more likes
Thank you so much man.
In these multiple-angle solutions, may n be negative? When there is 2 or more multiple-angle solutions, how do you immediately know when you can blend them into just 1 multiple-angle expression?
Thank you very much i have understood this you are awesome
Simply the best there is....👑
Thnak you so much bro u saved me ❤️
This channel is gold
Thank you!!!
Thanks got test today this has definitely helped me 😁
does it help you untill now tho
single handedly saving my math marks what a goat
you are the reason why i do good in ap calc
Thank you so much :)!
Thank you!
Sir, in your second example, I have two queries. The first is, is that the only method : dividing both sides of the equation by cos to work that problem, because I certainly did not do that. Couldn’t we have squared both sides as an alternative?
Second, aren’t you not supposed to divide by a trig factor - in this case COS X,since you may loose solutions???
Please explain thanks.
lots of love from India!!!
Your voice is so good also the teaching
Great video now im gonna pass my test woooo
This vid was amazing
i love you so much sir thank you for saving my life
SIr, I find something might be wrong at 2:56 in your video. I think 45-45-90 triangle's rate of sides should be 1:1:√2 instead of √2:√2:1
Yes you are correct, I believe he made a mistake there
Absolutely destroying calculus 1 when I've never been good at math, but the trig functions are starting to creep back into everything again. Gonna be a rough couple weeks being brought back up to speed on this, trig is honestly so wack.
10 hours before pre calculus final exam. This is the first studying I’ve done.
playing this on loop all night for my test tmr
Thank for this content! You’re awesome
hey, you're awesome too! :D
@@aet8950 poggers
I love maths trigonometry calculus ❤️❤️❤️
Thanks dude for the tutorial 💚🙏 it has helped me a lot*️⃣
Thank you so much 🥺🥺
After watching this video I can clearly understand trigonometric equation thanks for making this video
45 45 90 triangle the sides are 1, 1, and the sqrt of 2 is the hypotenuse
omg thank you bro
Thanks so much sir u just saved someone dat is to write an entrance exam😚😚
so in a way you can treat the trig functions as regular variables and then after isolating the trig function as much as possible, solve for x.
Thanks again
this shit is hard af. But i will ace this test if its the last thing I do
Thx so much
for the second general equation,how do you know when you have to find general solution for sin?
thank u so much sir
Thanks a lot
thank you so mcuh for your viddeos its really helping me
he messed up the sides in the 45 45 90
MA FOX
So I always thought:
2 times the square root of two was 1. I don’t know what you’re talking about.
Team Nolex the hypotenuse CANT be shorter than the legs.
Team Nolex 2 isn’t a square number therefore it can’t be one
Hi
1=4 haha
For the triangle of angles 45 45 90 the hypotenuse= square root 2 not the opp and adj
I’m sorry but this just didn’t help for my Pre-Cal study guide. I’m legit screwed🙃
No you're not, start by studying the sequences of the angles numbers go from there
Gloria Kiss i got a 93 on the test turns out I wasn’t as screwed as I thought
@@justinkongol0 and you're going to do even better because you are persistent and a perfectionist. You taste success ✊🏽💯
@@gloriakiss5823 i taste failure
Lesa akupale iwe😂😭, you just don't know how much you've helped
Well, at least I get a weekend to learn all of this
