This calculus video tutorial explains how to find the integral of cos^2x using the power reducing formulas of cosine in trigonometry. The derivatives of trigonometric functions are also necessary to determine the best way to simplify the expression. Integration by parts formula: ? u d v = u v-? v d u. int x^2cos^2xdx = x^3/6 + (x^2sin (2x))/4 + (xcos (2x))/4 -1/8sin2x +C When we integrate by parts a function of the form: x^nf (x) we normally choose x^n as the integral part and f (x) as the differential part, so that in the resulting integral we have x^ (n-1) In this case however cos^2xdx is not the differential of an «easy
Now that the general formula: ∫ cos ( a x) d x = 1 a sin ( x) + c has been established, the integral of cos (2x) is immediately evident by replacing a with 2: ∫ cos ( 2 x) d x = 1 2 sin ( 2 x
