    Exclamation trig functions: verifying identities

    how would you verify SIN(X)/ 1+COS(X) + SIN(X)/1-COS(X) = 2CSC(X)

    start with the left hand side. you are going to manipulate it until you get the right hand side.

    begin by combining the fractions, then simplify

    \frac{{\sin x}}<br />
{{1 + \cos x}} + \frac{{\sin x}}<br />
{{1 - \cos x}} = \sin x\left( {\frac{1}<br />
{{1 + \cos x}} + \frac{1}<br />
{{1 - \cos x}}} \right) = \frac{{2\sin x}}<br />
{{\sin ^2 x}}

    Can you take it from there?
