Summary:I have the expression sin(2x) + sin(2[x + π/3]) and I have to write this in terms of a single function (a single harmonic, rather saying). But I don't know how to do this, and... it seems a little bit weird for me, because I'm merging two sine-wave functions into one. Doesn't the sum of sines result in a more complex body than a simple sine alone?

Summary:

The exercise that I'm trying to solve says that I must use a trigonometry formula to solve.
