i got the critical pts actually, x=pi/3 and x=0
and for the inlfection pts its cosx=2 and cosx=3/4 ..is that possible?
find the critical points of f(x) and use the second derivative test (if possible) to determine whether each corresponds to a max or min.
i got f'(x) and f''(x) but im just having a little trouble setting them equal to zero and solving for the critical and inflection points. Could someone help me out on that please?
x=? -->critical pts.
x=? -->inflection pts
