@@banty6350 You can take the hypotenuse as any value, lets say 'x'. All lengths will change accordingly but at the end the value of 'x' will get cancelled out on both sides of the formula. Try it. So taking the value as '1' actually simplifies the process.
The proof is very common in youtube...what is NOT common is to prove why sin(A+B) WORKS FOR OBTUSE ANGLE or CIRCULAR FUNCTIONS (i.e in all quadrants) ? Also, why cos (-theta) = cos(theta) because negative angle is concept adopted by our mathematicians but strangely , it works !!!
General method here: ua-cam.com/video/Sa7jmAGes0Y/v-deo.html&lc=UgxbMONy7K6xB7w08Up4AaABAg Also there is a discussion in the comments section of that video which is related to your query about sin(A+B) formula for obtuse angles and other scenarios. Hope this helps.
For ease of calculation the hypotenuse is taken as 1. You can take it any value, accordingly the lengths of other sides will vary but their ratio will be same and the final result of the formula will be same.
easiest deriviation sir !!
thanku veryvery much sir
Amazing op sir 🔥🔥🔥
Making Sir, thank you very much for clarifying this
After watching many videos of the same proof here i understood more clearly. Thanq for the explanation
It truly means a lot to know that these videos are making a difference for students who are passionate about learning.
@@niteshjakhar but sir why you taken the length of hypertonuse equal to 1 ?

@@niteshjakhar it is proved for only this type of particular diagram or we can prove it with other diagram also. Thank you for your reply sir.
@@banty6350 there are other ways to prove it.
👌👌👌👍👍👍👍👍
wow fantabulous
Good video sir...Sir please video of sent sin(A-B)and
Cos(A-B)
What app do you use for teaching sir??
it's very beautiful ❤
All made in power point, thats it.
It's very easy method sir
🎉 🎉🎉🎉❤❤❤❤❤ very nice sir
Areh wahh
My goodness.this is the 1st time I got the 'feel' of the scenario.😅
BEAUTIFUL
❤️❤️
