Dividing Complex Numbers
Division is the same as multiplying by the multiplicative inverse. For a complex number a+bi, the inverse is 1/(a+bi), but it is helpful to transform this ito rectangular form:
So, if we have problem (a+bi)/(c+di), we actually have a+bi multiplied by the inverse of c+di. We can transform this to rectangular form also:
If you happen to be working in polar form instead, the calculation is much simpler, as you are simply dividing with the magnitudes and subtracting with the angles.
