# Math Help - Simple Integrals

1. ## Simple Integrals

I need help finding the integers of the following two equations. I figured them out but came up with the wrong answers when filling in the limits.
e^(1/x)/ $x^2$ limit here is 1 and 2
$x ln(x)$ the limits are 2 and 3

2. integers? ... maybe you mean integrals?

$\int_1^2 \frac{e^{\frac{1}{x}}}{x^2} \, dx$

use a substitution ... let $u = \frac{1}{x}$

$\int_2^3 x\ln{x} \, dx$

integration by parts ... $u = \ln{x}$ ... $dv = x \, dx$
