Help anyone? I need both sides to equal.
-2sinxcosx/ 1-sinx-cosx = 1+sinx+cosx
multiply the top and bottom of the left side by
1 + sinx + cosx
leave the top alone, but expand the bottom
at the bottom you will end up with -2sinxcosx which will cancel with the same at the top, leaving you
with 1+sinx+cosx which is RS
