How do I find the relative max on the interval 0<(or equal) X <(or equal) 3

when given the first derivative as:

f ' (x) = (e^(-x/4))(sinx^2)

where x is greater than or equal to zero

& f(5)=0

Because is differentiable everywhere and the domain contains no boundary points, relative maxima will only occur where

By a theorem in algebra, this occurs only where

Because is always positive, we are left with the cases in which
