  1. writing your equation the way you did is indeed a mathematical SIN

    Did you mean ...
    cscx - cosxcotx = sinx ?
    and are we proving the identity?

    If so, then
    LS = 1/sinx - cosxcosx/sinx
    = (1 - cos^2 x)/sinx
    = sin^2 x / sinx
    = sinx
    = RS

    Verify the identity. (csc(2x) - sin(2x))/cot(2x)=cos(2x) =csc(2x)/cot(2x) - sin(2x)/cot(2x) =csc(2x)/cot(2x) - cos(2x) Is this correct so far? If so then how would I continue? I got stuck on this part...
