Proof of 2sinxcosy=sin(x+y)+sin(x-y) | 2sinxcosy formula | trigonometry class 11

Hello Guys,
In this video i have explained 4 proof of trigonometry formulas are :
1) 2sin x cos y = sin(x+y) + sin(x-y)
2) 2cos x sin y = sin(x+y) - sin(x-y)
3) 2cos x cos y = cos(x+y) + cos(x-y)
4) 2sin x sin y = cos(x-y) - cos(x+y)

Thanks sir 🙂❤❤❤❤

[@Epselon]

Most welcome

[@travelsblog6386]

0:16 no. 2 formula and no. 3 formula same kaise hai sir?

[@Epselon]

In second formula there is a editing mistake
Please watch full video, i have explained it correctly in the later part
