## Main Question or Discussion Point

i have to integrate to find the electric potential due to a disk of charge with an uneven charge distribution. i was able to set up the intergral but i cant solve it. should i do integration by parts (i tried it) or use something else. just give me a hint

int ( r^3/[(x^2 + r^2)]^.5) dr (x is a constant)

thanks
