Alex: if you want to write a+bi you can write it as, (a^2 + b^2)^(1/2) * e^(it) and t = arctan(b/a) and then you can write e^(it) as cos(t) + isin(t) so the whole thing would be (a^2 + b^2)^(1/2) * (cos(t)+isin(t)) but it is more convenient to write a+bi as re^(it) where r = (a^2 + b^2)^(1/2) and t = arctan(b/a) Katya: alex, when i said that i did want to learn about imaginary numbers right now i...
