I need to state all extrema of y=x+sinx in the interval [0, 2Pi]
I think the first derivative f'(x)= 1+cosx and that the function f(x) has a relative maximum at (Pi, Pi)
The function f'(x) has maxima at (0, 2) (2Pi, 2) and minima at (Pi, 0) I think.
Answers I can choose from:
a. (-1,-1+(3Pi/2), (0, 0)
b. (2Pi, 2Pi), (0, 0)
c. (2Pi, 2Pi), (Pi, Pi)
d. (Pi, Pi), (0, 0)
e. none of these
It's not a I think because that point lies outside the limit. Do I need to look at the graph of f'(x) or f(x)??
