Find the absolute maximum and minimum values of the function

Question

b) g(x) = sin(2x) + 2 cos(x) on the interval [0,π/2].

Answer 1

First calculate g'(x)

Then find out where g'(x) = 0 or undefined. Reject any x-values that are not in your given interval [0,π/2].

Now compute g(x) for x=0, x= π/2, and the x values found above.The absolute max will be the largest g value found in the last step. Same for the absolute min.
