How to take integral of sin 2x
WebFind the integral int(x^2e^(2x))dx. We can solve the integral \int x^2e^{2x}dx by applying the method of tabular integration by parts, which allows us to perform successive integrations by parts on integrals of the form \int P(x)T(x) dx. P(x) is typically a polynomial function and T(x) is a transcendent function such as \sin(x), \cos(x) and e^x. WebCalculus. Evaluate the Integral integral of 1/2*sin (2x) with respect to x. ∫ 1 2 ⋅ sin(2x) dx ∫ 1 2 ⋅ sin ( 2 x) d x.
