so the expected area is given by
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
