Homework Help: How to find the integral of (3x^3 - 1)/x from 1 to e

  1. Apr 13, 2010 #1
    [tex]\int_{1}^{e} \frac{3x^3-1}{x} dx[/tex]

    What method? I haven't seen a problem like this before.

    Re: Integration

    Remember how (a+b)/c = a/c + b/c ? Use a similar principle.

    Ah, OK so:

    [tex]\int_{1}^{e} 3x^2 -\frac{1}{x} dx[/tex]

    In which case this becomes a simple integration problem.

    Thank you!
