$$f(x)=\sin(x)+2x-\frac{3x(x+1)}{\pi}$$

on the interval $[0,\pi/2]$ using the standard calculus techniques. There's one critical point near $0.88$, and then you have the endpoints. The left endpoint, I think, will end up being the smallest point on the graph. The second derivative might come in handy.
