    Re: Help with Trig. Identity Problem

    common denominator on the left side ...

    $\dfrac{2\sin{x}\cos^2{x}-\sin{x}(\cos^2{x}-\sin^2{x})}{\sin{x}\cos{x}}$

    change both $\cos^2{x}$ to $(1-\sin^2{x})$ in the numerator ... then simplify the numerator.
    Thanks from StefKeays and topsquark
