Polar Form of a Complex Number
The polar coordinates of
a complex number on the complex
plane. The polar form of a complex
number is written in any of the following forms: rcos θ +
irsin θ, r(cos θ + isin θ),
or rcis θ. In any of these forms r is
called the modulus or absolute value. θ is
called the argument.
