    Step-by-step explanation:

    Simplify RHS

    Cotx + 2tanx+tan^3x

    Cotx/sinx+2 (sinx/cosx) + sin^3x/cos^3x

    Taking LCM

    (cos^4x+2sin^2xcos^2x+sin^4x) / sinx cos^3x

    (Cos^2x+sin^2x) ^2/sinx cos^3x

    (1/sinx cos^3x)

    (1/sinx cos^3x) * (cosx/cosx)

    Cotx sec^4x

    LHS=RHS

    Hence proved
