( The Tan is inverse, i'm not sure how to properly display that in latex )
Is it right ? If yes
now how can I solve

The derivative of is and not .
To solve , simply add 1/subtract 1 (which is actually a shortcut around a polynomial division) to get:
Sorry if I sound a bit ignorant, but I don't really get it, I'm a bit new to all those stuff... could you explain a bit more? What did you add and what did you substract, and then what would i get ?
I divided the polynomials in this integral and i got
solution for that is x - ln | 1 + x^2 | + c
is this right ?
the integral of is
thanks a lot guys, eventhough i didn't understand Chop Suey method, but I'm glad i made some progress -,- just started learning integrals yesterday
