    please finish trigonometric equation.

    Can you show me where this goes, or start me on the right path?

    3cot^3x - cotx = \sqrt {3}

    \frac {3cos^3x}{ sin^3x}-\frac{cosx}{sinx}= \sqrt {3}

    \frac {3cos^3x}{ sin^3x}-\frac{cosx\times sin^2x}{sin^3x}=\sqrt {3}

    \frac {3cos^3x-cosx\times sin^2x}{ sin^3x}=\sqrt {3}
