# Math Help - stationary points

1. ## stationary points

a) use calculus techniques to determine all stationary points and their nature for the function f(x)=xsin(x) , -1<x<10

b) use calculus techniques to determine any non-stationary points of inflection for the above function

i got no idea how to do it help please

2. Are you taking a Calculus course? Do you have a Calculus textbook? If neither of those is true, I don't understand where you got this problem. If they are true, then the first thing you should do is look in your text book for the definitions of "stationary point" and "point of inflection". I suspect they are defined in the section preceding these problems.
