I used it to create this simplified equation in rectangular form: As well as using normal or real numbers, Complex Numbers were introduced to allow complex equations to be solved with numbers that are the square roots Then we can extend this idea further to show the definition of a complex number in both the polar and rectangular form for rotations of 90o.Polar equations give us a different mathematical perspective on graphing. In rectangular coordinates, we use two axes which meet at the origin and are perpendicular to one another. In polar coordinates, we start with a fixed point, O, called the pole or origin and then we construct an initial ray called the polar axis.
