all of these complex formulas, think of it on the xy (complex) plane and think of it as the y value being the coefficient of i, then you graph it and use a^2 + b^2 = c^2 to get the magnitude and your soh cah toa to get the angle
thinking of it this way will make stuff a lot easier... i guess i could make a pic if you need it
