I just sketched y=|sin(x)| using graphmatica and the sharp points seem to be at the x axis. I hope that's answering the question.

y=(sinx)2=(f(x))2

dy/dx=2f'(x)f(x)

thus the x coordinates of y=f(x) become x coordinates of turning points for y=(f(x))2

also, the x coordinates of the original turning points of y=f(x) remain to be the x coordinates of the turning points of y=(f(x))2
