Nice!

its 1am and my brain is fried so quick question why is alpha in the green triangle?

Proof sin(a+b) in unit circle taking (a+b) greater than 90 degree

чітко! дякую

this is a beautiful proof

Wonderful, easy and fluently proves. Especially I like it because you showed it with using unit circle.

Skp to 3:00 if you just want the proof without a lengthy into

Very sad to see you post no more,,,, what happened to you?

thanks

..... طريقة ممتازة للبرهنة....... وتبدو سهلة لفهم كيف تستنج العلاقات المثلثية لمجموع زاويتين..... اعرف طريقة الجداء السلمي..... وتعلمنا طريقة اخرى...... لكن هذه جميلة جدا...... تعلمت طريقة المستطيل وحساب مساحات... داخل مستطيل.... الانترنات.... سهلت الكثير لمن يريد التعلم...... فكيف يكون الحال مع الذكاء الصناعي......!!!!؟؟؟؟

Dude, that criminal/non-criminal comment is hilarious

Excellent!

oh i can see!!

I couldn't agree more with u on the understanding part. Good video

thank you

too good bro too good

Thanks. One of best explanation

thank you bro

great explanation.

This is great but the real answer is when you look at a problem you see the square and reverse derive all counterrelations and sum or subtract when you need to get. Not for stupid people. Mnemnoics are just fine for <3sigma. don't sweat the big stuff.

Total ly green blur😭

nice video good work .... please what is the name of the program you use

Ingenious

훌륭한 가르침. 감사합니다.

Is this visual representation enough as a proof?

it is very good explanation

Thx

THANK U VERY MUCH SIR! !

👏👏👏👏👏👏👏👏👏👏👏💛

Thanks very much for this. Very helpful.

Thank you sir

Awesome proof!!!

well explained

Here i found mathematics

I love this proof... its clear and clean.... its intuitive and insightful... let me state the obvious for anyone who is as blank as myself... each 90deg is composed of (alpha, beta and gamma)... once you identify any 'single term' in any of the triangle... the other angles are either a 90deg right angle... or a composition of the two missing terms... hope I helped someone.

Nice explanation

Mind = Blown

I spent hours trying to find a more visual, intuitive explanation for the sum and difference identities and couldn't find anything beyond algebraic proofs (which helped a little to show where the identities derived from but did little to elaborate on their relationship to something tangible). Thank you for your video! I never comment on videos but this was such a big help to me and my understanding of this topic. So glad I found this before my exam tomorrow 🙌

Which software is this????

This is because the teacher doesnt care to take the time to teach this to us

Very clear and very helpful, thank you.

Very nice. In single concept, two proofs are done.

great job

Amazing

I have searched for an intuitive explanation of this concept, and I have to admit, this is very clear and insightful.

Stupid explanation

Beautiful explanation!

Very nice!

I guess I am going to jail for a long time

Excellent video. Thank you.
