@rob1525  do you think you can help ?

I hope so. I think what your asking is to simplify the two sin terms into their simplist form. when sin has 2x inside you can use the double angle formula to convert to just x and the second term where x-2 you can use the difference angle formula to convert. Heres a website with the formulas: http://www.sosmath.com/trig/douangl/douangl.html *note that they use a instead of x.
