Originally Posted by Boo Please, I search for stationary points of f(x)=sin^3xcosx I got x +kpi x/2 +kpi Do you mean that $\displaystyle \sin^3(x)\cos(x)$ is the derivative? Or is that the function for which you are to find stationary points? If it is the second the neither of those is the answer.
No, sorry, points of inflection!!!
