- 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 for watching 🙏
Thank so much sir yah meri Sabse badi problem thi mujhe sin cos solve karna nahin aati thi😊😊😊😊
Mast❤
Very good teaching 👍 👏 👌 😊
Thanks sir 🙂❤❤❤❤
Most welcome
0:16 no. 2 formula and no. 3 formula same kaise hai sir?
In second formula there is a editing mistake
Please watch full video, i have explained it correctly in the later part
