hey mates try to solve it...​

Answer 1

so it is clear to you

step by step explanation

thankue

Answer 2

$\huge\boxed {Answer}$

LHS :-

Sin5x - 2Sin3x + Sinx / Cos5x - Cosx

(Sin5x + Sinx) - 2Sin3x / Cos5x - Cosx

{(2Sin3x * Cos2x) - 2Sin3x }/( -2Sin3x*Sin2x)

=> -2Sin3x(1 - Cos2x) / -2Sin3x * Sin2x

=> (1 - Cos2x) / Sin2x

=> 1/Sin2x - Cos2x/Sin2x

=> Cosec2x - Cot2x

=> RHS
