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)/$\displaystyle x^2$ limit here is 1 and 2
$\displaystyle x ln(x)$ the limits are 2 and 3

integers? ... maybe you mean integrals?
$\displaystyle \int_1^2 \frac{e^{\frac{1}{x}}}{x^2} \, dx$
use a substitution ... let $\displaystyle u = \frac{1}{x}$
$\displaystyle \int_2^3 x\ln{x} \, dx$
integration by parts ... $\displaystyle u = \ln{x}$ ... $\displaystyle dv = x \, dx$
