Simplify: sin(A+x) sin A + sin B - sin(A+B) sin x sin A - sin B + sin(A+B) -------- * ----------------------------- + ----- * ------------------------- sin A sin B + sin(A+x) - sin(A+B+x) sin A sin(A+B+x)+sin(A+B)+sin x You will know you have found the simplest form when you find it. This problem arose while solving another problem. It can be greatly simplified by computer, but it took over 5 minutes of heavy computation. Yet the question seems elementary enough that any high school student can work on it.
