Find any stationary points of this function and state whether they are local max or min.
g(x)=(e^(-3x+2sinx)/6)/(3+2cosx) 0<x<2pi included.
Just in case a picture helps with the quotient rule...
... where (key in spoiler) ...
Ignore the denominator, and the exponential which can't be zero. So you have...

Finding the +/- sign of the second derivative at these points determines whether the curve is, following it left to right, headed ultimately up (because turning out of a minimum) or down (coming out of a maximum). (The 'second derivative test'.)
But determining whether min or max is often (probably here) easier just by testing the values of the original function around the stationary point.
