    Exclamation 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

    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
