**[SOLVED] Stationary points**

## Homework Statement

Does the funtion g(x) = x + sin(x) have any stationary points on the interval [-5,5], if so where?

## The Attempt at a Solution

Stationary points is where there is a 0 slope so here is what I did. Just need someone to check to see if this is right.

g'(x) = 1 + cos(x)

cos(x) = -1

So for the answer I got two stationary points at pi and -pi.
