Brilliant explanation! Clear and concise…a natural teacher!
You did a much better job of teaching this then they did in college - for free
The Unit Circle BLEW MY MIND! Why no one ever taught me that!?
I'm curious how you were taught? :D
This video is a little gem. Informative, short and easy to understand. Very well done
I was impressed with the first 1:30. I really like the layout of the video.
This was a rather great revision video for me! Thank you.
There is a book in you. You must put these "Must Knows" into a book! The book should be short and concise or without any unnecessary words!
Does it even feel good riding that hard?
Bad idea. Video is better than books.

Who buys books?
You're watching a video.

Thank you so much Jensen- I directly suscribed after watching this goldpiece! So helpful!
Well said. Thank you very much for sharing with us.
I am a 8th grader and I loved the explanation,pretty simple.
keep striving for knowledge my dude, i'm in my second last year of high school trying to pick up my grades... maths is a fundamental thing to learn 💪
I am in 7th grade, and i am understanding it very well.
THE BEST VIDEO SO FAR! KEEP IT UP!! YOU GAINED ONE SUBSCRIBER ❤️🔥
This is the best video on the best channel I have ever discovered on TH-cam. Keep it up! As an 8th grader, I have learned all of trigonometry and calculus via TH-cam. This video helped me a lot.
Been there! Out of anger 😅
same lmao
You dont need calculus or trig in grade 8 💀. Where are you from bro?
Good on you. Wish I had this in 8th grade. Instead of clueless teachers.
Pay no attention on jealous haters. 😁
@@JonnyBoi957 Curiosity is a thing bro.
very informative and helpful video. Thanks a lot for sharing your knowledge.
Bro just did the work, which my advance level techer took 6months🗿
Bro explained so good that i had to subscribe even though i don't study these anymore. Hat's off to you 🎉👌
Do a vector video next targetting Grade 11 and 12. Love the videos!
Nice. Well done. Good review.
Thankyou so much sir ❤this helped me a lot in my invs. Trig
I thank you for such productive lesson...
the best video on this topic so far
Thank you so much Sir❤
Excellent! One suggestion is to rewrite Cosine law in simpler and straight forward manner:
Cos A = (b^2 + c^2 - a^2)/2bc
That is just blind memorization. Whenever I need to use cosine law to find the third side of a triangle opposite to an angle (Say A) I think of it more as a 'Find the hypotenuse ' problem except the hypotenuse is opposite to the angle A instead of 90°. This makes more sense to me and I can setup the problem correctly without any doubt.
Thank you so much sir.
Good choice of top 10.
can you do one of these for grade 10 analytical geometry?
🎉thanks for the video
It was magic ❤ thank you sir ❤
You made it so simple
Love you Sir ❤️
This man cleared all of my concepts I knew all these things but didn't know the real reason behind these equations and terms, I feel like I knew nothing
Great video
Noted!
Dear Jensen, thank you for your efforts. As a teacher myself, I understand the work behind this awesome teaching.
Can I ask you which teaching tool are you using. For instance @ 3:40 (must know number 2) you were able to scale the right angle triangle without scaling anything else on the screen.
FYI, I use ppt and various transitions for the animation effect.
Pls. shed some light
Thanks 🙂
Excellent
Great,sir♡♡.
Thanks bro
Brilliant💯💯
well done !
Sir I finally get the derivation❤
#1 no triangle is what it looks like until you can prove it numerically.
Took me up highschool to understand this.
Kindly give how do you prepare these slides, and prepare a video.
Please make one more detailed video about trigonometric functions
It has been a while since i have done trig and was looking to brush up. @ around 8:08 - 8:50, you got approxametly 50.8 degrees. I got around 42 degrees. This comes to A = Cos^1(-283/-384) which = aprox .7422 rad or 42.5 degrees. Am I wrong?
Hi Could you make a video on its graph how it is made from scratch... please
Thanks for the effort man ❤, but that's not all trigonometry, as far as I remember there are rules for sine(X + Y ) , and cos(X + Y ) and other trig functions
thanks
It’s funny on the date that you posted this video I took my trigonometry finals that day and I made a 100%. Thank you so much for posting this video. I’m sure it would help many people to ace their trig finals as well. BTW I’m 51 years old taking electrical engineering. I started this journey last semester with my college algebra, which I also got a final score of 100%.. next semester calculus 1
Wow inspiring! I am 38 and want to do something similar but unfortunately here in India we have very rigid educational system
Sir,Your explaination style is very clear Can you make a class10th series(mathematics) for India
I mean it's up to you but it would be much better to learn from you😁
I thought similar triangles was in geometry but you say it is tricknometry. I now to your superior knowledge
You almost formed a sentence, congratulations.
Is it for a university (math department) or high school level, If the latter is true, a lot of gaps are identified. Your reply
I must be missing something.
I have a triangle with known angles, 90 60 and 30, and a single known side length of 3 between the right angle and the 30.
If the 30 is the reference angle, 3 is the Adjacent side therefore 3=a.
I want to solve for the Hypotenuse, so h=x.
I try to apply sine law.
x is the hypotenuse, and the angle opposite the adjacent is 60, so x/sin(90) = 3/sin(60).
Some balancing and x = 3sin(90) / sin(60)
Which comes out to approx. -8.799
Which does not look even slightly correct.
Just eyeballing my triangle, the hypotenuse should be slightly more than 3. I almost expect it to come out to pi.
It should not be more than double the length of the known side and also negative.
What am I doing wrong?
You are correct about the answer being a little more than 3. I'm no math wizard. I learned a much more simple approach to trig. From my limited understanding though, you would want to choose Cosine to work with. The SOH, CAH, TOA choice is determined by which corner you are working from and the results you need to know. Working from the 1) 30° corner , 2) you know the adjacent side, 3) you want to know the Hypotenuse. You choose to use CAH since this formula uses both the known side(Adjacent) and the unknown (Hypotenuse) side. Plug this into your calculator and you will get the number you suspect.....hope this helps you.
when do i arctan(8/17) i get something like 0.4
Edit: just found out my calculator was on radians nevermind
Brilliant explanation…you didn’t had to end it with that Jensenmath track though.🥺
This popped up only after I finished my trig course.
Mmmmmh. Math 😊 🤩.
🎉
❤❤❤❤
👍
got in trouble many years ago at school when asked to find the angle' i said use a protractor it was not the answer the teacher wanted' i still stick with that maxim why go through all that hassle ? as you can tell this nonsense was not my fav' subject , simplification rules over complication ...........
W video
I want coordinate geometry
Superb bro, but the intro tho
What intro
Great explanation masha Allah
I am in algebra why did I click this
Trig reference
Sahi padhate hai ye
7:38 the background makes it hard to see
I use Sex And The City instead of CAST.
Good explanation, but incomplete
3:18 socahtoa?
It's Pakistan Bhuka Pyasa

doesn't matter
Bro speed running wrong chapter 💀
Which one
Why is math more fun when we are adults
You arent forced by law to do it
I really hate to memorise ABCD line in the description.
