The Attempt at a Solution
I tried finding the derivative and setting it equal to zero.
y' = 3 + 6(cosx)
3 + 6(cosx) = 0
but I'm not sure where to go on from here, the book only has 1 example which doesn't clear much up.
also how do i write equations to make them look like some of the other posts I've seen(equation text lookΦ).
