find this problem really though. I did solve for it's derivative and then by EVT tried to find its crititcal points. I get (π/2) and (π/2) for f'(x)=0.
The problm is that I'm not sure if there are more solutions for f'(x).
Please see function in problem 1 of attachment:
Any help will be greatly apreciated.
Thank you.
