Question
If f(x)=sinxcosx, what are the critical points? on the interval (o, 2pi)

Critical points are points in the given interval (0,2π) at which the derivative is zero, or the function is not differentiable.
The function f(x)=sin(x)cos(x) is differentiable from (-∞,∞), so you only have to look at the points at which the derivative is zero.
