    Verifying trig identities

    cosxcotx / 1-sinx = cscx+1
    Whenever I do it I keep on getting sinx+1 instead, I'm not sure what I'm doing wrong.

    Re: Verifying trig identities

    $\dfrac{\cos(x)\cot(x)}{1-\sin(x)}=$

    $\dfrac{\cos^2(x)}{\sin(x)(1-\sin(x))} = $

    $\dfrac{1-\sin^2(x)}{\sin(x)(1-\sin(x))} = $

    $\dfrac{(1-\sin(x))(1+\sin(x))}{\sin(x)(1-\sin(x))} = $

    $\dfrac{1 + \sin(x)}{\sin(x)} = $

    $\csc(x) + 1$
    Thanks from topsquark
