2. let u = x
du/dx = 1
du = dx

let dv = e^(2x)dx
dv/dx = e^(2x)
v = (1/2)e^(2x)

formula:
[int] u dv = uv - [int] v du
[int] x e^(2x) dx = (x)(1/2)e^(2x) - [int] (1/2)e^(2x) dx
= (1/2)xe^(2x) - (1/4)e^(2x)

evaluate the integral: y lny dy i know it's integration by parts but i get confused once you have to do it the second time Leibnitz rule (a.k.a. product rule): d(fg) = f dg + g df y lny dy = d[y^2/2 ln(y)] - y/2 dy ----> Integral

How do you find: the Integral of arcsin(1 / (sqrt x^2 - 1) ) dx ?? (The integral of arcsin of one over the squareroot of x squared minus 1) So far, I've used trig integration to simplify down to arcsin(1/tanb) *secbtanb b is theta

how do you start this problem: integral of xe^(-2x) There are two ways: 1) Integration by parts. 2) Differentiation w.r.t. a suitably chosen parameter. Lets do 1) first. This is the "standard method", but it is often more tedious
