Find the exact value of the area of the region enclosed between the x−axis and the
graph of the function f(x) = 2 sin x + 2√3 cos x on the interval [0,π].
HINT: It might be helpful to first write f in the form f(x) = Asin(x+K) for appropriate
constants A and K.

K=phase
A=amplitude

in the range the graph is sometimes above the x-axis and sometimes below it,
use the hint to find out when.
Then use integration to find separately the areas above & below the x-axis
