Gerald,
One example might be where you need to divide two complex numbers  for
example you want to calculate (a+jb)/(c+jd); that requires some tedious
maths.
However if the complex numbers are expressed in polar form: (w @ angle
x) and (y @ angle z), the answer is simple: w/y @ angle(xz)
The engineers amongst us will be very familiar with swapping between the
two forms and using whichever is the easier to manipulate in a
particular calculation.
We often use the polar form without realising it; for example a
resistance of 40 ohms in series with a reactance of 30 ohms gives a
total impedance of 50 ohms. We've unwittingly moved from the 40+j30
form to the 50@angle37degrees polar form.
