Area of a Triangle (Deriving the trigonometric formula)

[MoominAlice]

This is amazing! At my school we always learn "1/2ab×sin(C" and other things but never why. You always explain it so clearly and so well, thank you

Just one video and I am already impressed by how you teach.

You're such a good teacher! Students are lucky to have you as their teacher. :)

Haa finally! After minutes of looking for the right video I finally found this onee!! Its so straightforward and fast, love it.

I need this to remind me of the stuff I learnt and effectively forgot 5yrs ago.

I don't suppose it's necessary but having a 2nd camera might make your videos more visually interesting but otherwise, this is good.

Hello sir, I am a Bachelor of Computer applications students
But still I watch ur videos .
I just love ur videos, except these topics are not in my course though.

Your students are very lucky!! These videos are super helpful to your students and other students. Congratulations!!!!

I liked the idea of linking the the right angle triangle with the unit circle and the non right angle triangle

Your students are lucky to have u ♥️♥️

fast way to get the sine law from this using this formula.

write the area formula using all three angles : ( 1 / 2 )ab sin C = ( 1 / 2 )bc sin A = ( 1 / 2 )ac sin B

Now multiply all of them by 2 : ab sin C = bc sin A = ac sin B

divide all by abc : ab sin C / abc = bc sin A / abc = ac sin B / abc
sin C / c = sin A / a = sin B / b

thank you so much ! this solve my lead compensator problem in control system subject.

How we prove 1/2 bxh.U proved this by using formula.but mathematician derivatives formula how?
