a) Determine where the function is increasing and decreasing.

b) Determine where the function is concave up and concave down.

________________________________________

I know:

f′(x)=cos(x)+2sin(x)

f″(x)=-sin(x)+2cos(x)

Other than that^^ I have no clue how to get the intervals where the function is increasing/decreasing and where it's concave up/concave down.

The function is increasing where f' > 0

The curve is concave up where f'' > 0.

Now just check 'em out.
