Omg, I need this! When I learn Maths, I’d rather understanding things than remembering things. However, most teachers just told me to remember it cuz it’s easier. You help me especially with the animation, you made it look so simple. Thanks!
Thank you for making this! In a right angled triangle, we define sinx as opposite over hypotenuse. In this non-right triangle, what is sin2A defined as? Is it the same definition?
I am using the law of sines. This doesn’t need a right angle; it works in any triangle. I have a visual proof on the channel about law of sines if you aren’t familiar with it.

Glad it helped!
Thank you for this proof. Understanding how to get to the identity instead of directly memorizing the identity helped me a ton
Glad this helped!
Superb visual proof! Thank you.
Thank you too!
initially, area of green triangle
= 2 * 1/2 * sinX * cosX
in terms of base and height
= 1/2 * 1 * sin2X
...
So simple and elegant. Love it!
Glad you like it!
So easy with visual proof, saves the brain power for more tricky stuff later on lol.
great proof, thanks
Glad you like it!
Great explanation!! Much obliged
Glad it was helpful!
Useful. Thank you.
Glad it was helpful!
Pww of sum to product trig identity, did you make one of it?
I have one in the works…
Thank you so much, it's awesome! I need a video about tangent and cotangent too🥴
👍

Gracias. Con los gráficos es más entendible ( con masa para comprender).
😀👍
nice!
Thanks for checking it out!
now how do you prove the law of sines and cosines... 🤔
Check my channel!
How can you consider sin from 2 times of the angle when the right angle is not guaranteed?

@@MathVisualProofs Thanks!
Love this!
👍😀
why sin(pi/2-0) = cos0 ?
ok i got it

Professor, I would like to activate the translation into Arabic, so that I can understand the explanation, your Arabic follower
