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!
