What is rectangular notation?

Rectangular notation denotes a complex number in terms of its horizontal and vertical dimensions. ... In rectangular notation, the first quantity is the “real” component (horizontal dimension of the vector) and the second quantity is the “imaginary” component (vertical dimension of the vector).

What does rectangular form look like?

The form z=a+bi is called the rectangular coordinate form of a complex number. The horizontal axis is the real axis and the vertical axis is the imaginary axis. We find the real and complex components in terms of r and θ where r is the length of the vector and θ is the angle made with the real axis.

How do you convert rectangular form to polar form?

How to: Given polar coordinates, convert to rectangular coordinates.

1. Given the polar coordinate (r,θ), write x=rcosθ and y=rsinθ.
2. Evaluate cosθ and sinθ.
3. Multiply cosθ by r to find the x-coordinate of the rectangular form.
4. Multiply sinθ by r to find the y-coordinate of the rectangular form.
