**Critical Points, intervals, local max/min help!! Calculus.**

**1. I need help with a homework problem that I just cannot get right. It asks: Answer the following questions about the functions whos derivative is given below.**

f'(x) = (sinx +1)(2cosx +[itex]\sqrt{3}[/itex] ), 0[itex]\leq[/itex]x[itex]\leq[/itex]2∏

f'(x) = (sinx +1)(2cosx +[itex]\sqrt{3}[/itex] ), 0[itex]\leq[/itex]x[itex]\leq[/itex]2∏

**a. what are the critical points of f.**

b. on what intervals is f increasing or decreasing?

c. What points, if any, does f assume local max/min values.

b. on what intervals is f increasing or decreasing?

c. What points, if any, does f assume local max/min values.

**I'm extremely confused with how to find critical points and max/mins. Help is greatly appreciated!**
