well, i think it's not that complex since the graph i made that is correct is just one that goes down diagonally... so, it's basically the graph of x-iy since x^2 and y^2 are basically a whole number...

1/z is 1/(x+iy) however, i then multiply by the complex conjugate and get: (x-iy)/(x^2+y^2) now, how do i graph this? thanks.

hi, why is ln|x|, from -1 to 1, converging? is "0" the bad point, and must i break up the integral from 1 to $, where $ = 0, and from $ to -1... so i have xlnx-x as my derivative... and i get -2? thanks

nvm, i got it

thanks! i get now to INTEGRAL(u * sin(u)) du ok, so now what should I do? thanks James

Hi, i am stumped on how to start this: integration of sin(ROOT(1 + x)) so, basically sin of square root 1 + x thanks James
