The question does not hold good for a correct answer because if

(cot x+cot y)²=(sin x+cos y)²

Then, cot x+cot y= sin x+ cos y

Which is not possible


Ojusoni: sorry I write cosy instead of siny
dhruvbadaya1: Can you rewrite the correct question???
Ojusoni: ohkk
Ojusoni: prove that (cotx+coty)^2 = (sinx-siny)^2
dhruvbadaya1: Hey! Then also it's not possible as this would mean cot x+cot y=sin x+sin y
