How to solve integral of e x 2
WebPractice set 1: Integration by parts of indefinite integrals. Let's find, for example, the indefinite integral \displaystyle\int x\cos x\,dx ∫ xcosxdx. To do that, we let u = x u = x and dv=\cos (x) \,dx dv = cos(x)dx: \displaystyle\int x\cos (x)\,dx=\int u\,dv ∫ xcos(x)dx = ∫ udv. u=x u = x means that du = dx du = dx. WebI used integration by parts and separated the integral to x * (x * e^-x^2/2) Then I got stuck when that creates the integral of e^-x^2/2 but apparently this is almost equal to "erf" (something I never heard of before!) erf(x) = 2/sprt(pi) integral(e^-t^2) By making that substitution I got the result of the integral:
