The value of the definite integral int (0)^(pi//2) ((1+ sin 3x)/(1+2 sin x)) dx equals to:
let 3x = u => 3 dx = du (after derivation) or dx = 1/3 du => ∫ sin 3x dx turned as∫ sin u X 1/3 du or 1/3 ∫ sin u du which is 1/3 (-cos u) + C, where C= constant of integration Substituting values again, we get ...
