[SOLVED] Stationary points 1. The problem statement, all variables and given/known data Does the funtion g(x) = x + sin(x) have any stationary points on the interval [-5,5], if so where? 3. 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.
