lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

\frac{1+Cos2x}{Sin2x}

We have to verify the identity.

We know that

1+Cos2x=2Cos^2 x

Sin2x=2SinxCos x

Using the formula

\frac{2Cos^2x}{2SinxCosx}

\frac{Cosx}{Sinx}

Cot x

By using the formula

Cotx=\frac{Cosx}{Sinx}

LHS=RHS

Hence, verified
