I assume this is the initial equation:
%28sin%28theta%29cos%28theta%29%29%2F%28cos%28theta%29-cos%5E3%28theta%29%29

simplify the following expression
sine theta times cos theta divided by cos theta minus cos^3 theta
***
sinxcosx/cosx-cos^3x
=sinxcosx/cosx(1-cos^2x)
=sinx/(1-cos^2x)
=sinx/sin^2x
=1/sinx
=cscx
