All of TRIGONOMETRY in 36 minutes! (top 10 must knows) 

Brilliant explanation! Clear and concise…a natural teacher!

You did a much better job of teaching this then they did in college - for free

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!

This is the best video on the best channel I have ever discovered on RU-vid. Keep it up! As an 8th grader, I have learned all of trigonometry and calculus via RU-vid. This video helped me a lot.

This video is a little gem. Informative, short and easy to understand. Very well done

This was a rather great revision video for me! Thank you.

Thank you so much Jensen- I directly suscribed after watching this goldpiece! So helpful!

The Unit Circle BLEW MY MIND! Why no one ever taught me that!?

THE BEST VIDEO SO FAR! KEEP IT UP!! YOU GAINED ONE SUBSCRIBER ❤️‍🔥

Excellent! One suggestion is to rewrite Cosine law in simpler and straight forward manner: Cos A = (b^2 + c^2 - a^2)/2bc

Bro explained so good that i had to subscribe even though i don't study these anymore. Hat's off to you 🎉👌

Well said. Thank you very much for sharing with us.

just an amazing video! the explanations are as smooth as butter amazing work! thank you so much

very informative and helpful video. Thanks a lot for sharing your knowledge.

I am a 8th grader and I loved the explanation,pretty simple.

Do a vector video next targetting Grade 11 and 12. Love the videos!

I was impressed with the first 1:30. I really like the layout of the video.

Thankyou so much sir ❤this helped me a lot in my invs. Trig

2 days before my exams im here... wish id found this earlier.. hopefully i remember it all on the day and i dont break down because the exam is in chinese (mandarin). regardless, thanks for making me understand this which i've never done before

Top Ten Must Knows for Vectors, please and thank you.

Bro just did the work, which my advance level techer took 6months🗿

I'm from ethiopia the video takes very important formulas and tricks,but in my opinion instead of CAST - All Students Take Chemistry (ASTC) is unforgettable. Thanks

Thank you so much Sir❤

Thank you so much for making this video. This helps a lot. 😎💗

can you do one of these for grade 10 analytical geometry?

I thank you for such productive lesson...

Thank you so much sir.

Fantastic. Thank you

the best video on this topic so far

Nice. Well done. Good review.

🎉thanks for the video

0 45 60 90 180 360 tan x =i pefer circumferences of partially spherical objects -such as of a circle like pie

Amazing. Please make for all types of function

It was magic ❤ thank you sir ❤

Love you Sir ❤️

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 🙂

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

Brillaiant video! Regarding for tangent law, does it relate to sine and cosine.

You made it so simple

Good choice of top 10.

Please make one more detailed video about trigonometric functions

Noted!

Thanks bro

Great video

Kindly give how do you prepare these slides, and prepare a video.

Thank you 😭

well done !

Great,sir♡♡.

Excellent

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

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😁

Excellent..

Brilliant💯💯

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

Hi Could you make a video on its graph how it is made from scratch... please

#1 no triangle is what it looks like until you can prove it numerically. Took me up highschool to understand this.

I thought similar triangles was in geometry but you say it is tricknometry. I now to your superior knowledge

Must Know #1: I'd have simply said that because lines BC and DE are parallel, just know that BC / DE (which is 10 /4) would tell me the ratio (or the multiplier to use). So, 10 / 4 is 2.5, that's the multiplier to use on line DA (which is 6) to work out the length of line BA. So, 6x2.5 = 15. We know the long line DA is x +6 , and we know the length is 15, so x = 15-6, which is 9. It takes longer to explain it to actually do it as you can do it in literally seconds!

thanks a lot you saved me from failing

Brilliant explanation…you didn’t had to end it with that Jensenmath track though.🥺

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?

Well explained then my college teacher

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?

Is it for a university (math department) or high school level, If the latter is true, a lot of gaps are identified. Your reply

thanks

Sir I finally get the derivation❤

This popped up only after I finished my trig course.

when do i arctan(8/17) i get something like 0.4 Edit: just found out my calculator was on radians nevermind

❤❤❤❤

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 ...........

🎉

Mmmmmh. Math 😊 🤩.

👍

I want coordinate geometry

Superb bro, but the intro tho

im in y10 with my math calculator mock tomorrow im gonna fail for sure

W video

Trig reference

Sahi padhate hai ye

I am in algebra why did I click this

I use Sex And The City instead of CAST.

Why is math more fun when we are adults

just one question why on earth we need a similar triangle in real life ?

Good explanation, but incomplete

3:18 socahtoa? It's Pakistan Bhuka Pyasa Hindustan Hara Bhara P/H , B/H, P/B

7:38 the background makes it hard to see

Haha. I honestly expected an indian accent before clicking on this video. 😂

I really hate to memorise ABCD line in the description.

Bro speed running wrong chapter 💀

Great explanation masha Allah
