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

[@celinehosea]

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

[@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

[@lilian7523]

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.

Kategari heh i learn't this 6 months ago :)

Your students are lucky to have u ♥️♥️

[@atakanbaykal775]

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

[@oscaristhecoolest28]

Thanks sir, had a test and I passed!

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.

This helps so much.

[@muhammadshafi2611]

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

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

Thx u very much

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

[@wildreams]

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.

You are cool

[@nwgverified]

Oh yeah that makes sense lel

[@mdkhalid-yu8if]

How do you speak English?

[@swagestmoodmaker]

He’s Australian. Apparently us Aussies also speak the commonly spoken language known as ‘English’
