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.
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
You can do that by recognizing that there are 3 general cases of triangles: Case 1: Right angle triangles. (simplest: Area = 1/2 of a rectangle) Case 2: Acute angle triangles. (Area = sum of 2 half rectangles) Case 3: Obtuse angle triangles. (Area = 1/2 large rectangle - 1/2 small rectangle) Using some algebra, you will realize that all cases leads to (1/2)bh; after you factorize and simplify. It's quite simple actually. Why not try this yourself with a pencil and paper? :)
I think you know how to find the area of a rectangle. l*b. So triangle is half of rectangle, ie, 1/2 lb. Now, its for right angled one. For other types, just make two imaginary right angled triangles and add them up.
Just one video and I am already impressed by how you teach.
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
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.

Kategari heh i learn't this 6 months ago :)
Your students are very lucky!! These videos are super helpful to your students and other students. Congratulations!!!!
Hello sir , I am a Bachelor of Computer applications students
But still I watch ur videos .

This helps so much.
I liked the idea of linking the the right angle triangle with the unit circle and the non right angle triangle
thank you so much ! this solve my lead compensator problem in control system subject.
Your students are lucky to have u ♥️♥️
Thanks sir, had a test and I passed!
Thx u very much

You are cool
Oh yeah that makes sense lel
How we prove 1/2 bxh.U proved this by using formula.but mathematician derivatives formula how?

Hi
How do you speak English?
He’s Australian. Apparently us Aussies also speak the commonly spoken language known as ‘English’
