**1. The problem statement, all variables and given/known data**

Find any points of inflection for the function y = x - cos x on the interval {0,2pi}

**2. Relevant equations**

**3. The attempt at a solution**

Well i know the second derivative is cos x, and I know it equals 0. But im just not sure what to give as a final answer. cos x = 0 at pi/2 and 3pi/2 but is that the final answer?

Thank you for your help!
