roots of (27 cis(pi/2) )^3 = (27 cis(pi/2) )^(1/3)

apply de moivre's theorem

roots on an argand diagram:

Put the words 'eBook' and 'torrent' after it in Google. I haven't paid for any non compulsory course book yet.

Probably scaremongering by the university. You can bet at least 50% of the people on your course won't have done the prep learning and the first few weeks will be slow as schiit so they can catch up.

No seriously, I first read it about a year ago but put it on hold because I haven't learned vectors and complex numbers that time.
