i feel so ashamed that i can't remember but i took calculus so long ago. is it simply ln(x^2)?

integral of (1/x)^2?...lol i'm too lazy to solve it but you do it via "integration by part" good luck

no, not quantity square. just one over x-squared. or 1/(x^2)

Lol you realize that's the same thing right?

Well considering 1/x^2 is the same as x^(-2), you add one to the power and bring the power to the front, but flip it. So therefore its "-x^(-1) or -1/x" + C

webmathematica is your friend... I've put some NASTY things into that site and it's given me integrals... like

Int(e^-(arctan(x^sin(csc(x^2 - 2 ln(cot(x))))))) except it goes on like that for about 5 times as long... and it's found the integral for me.
