#### Convert rectangular equation to polar

## How do you convert from Polar to Rectangular?

To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) 😡 = r × cos( θ )y = r × sin( θ )

## What is a rectangular equation?

A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane. For example y=4x+3 is a rectangular equation.

## What is polar and rectangular form?

In Rectangular Form a complex number is represented by a point in space on the complex plane. In Polar Form a complex number is represented by a line whose length is the amplitude and by the phase angle.

## What is the difference between rectangular and polar coordinates?

Rectangular coordinates, or cartesian coordinates, come in the form (x,y). Polar coordinates, on the other hand, come in the form (r,θ). Instead of moving out from the origin using horizontal and vertical lines, we instead pick the angle θ, which is the direction, and then move out from the origin a certain distance r.

## What is polar form?

The polar form of a complex number is another way to represent a complex number. 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.

## How do you graph polar equations?

r = a sin 2θ r = a cos 4θ If n is an odd integer, then the rose will have n petals. Example 1: Graph the polar equation r = 1 – 2 cos θ. Solution: Identify the type of polar equation The polar equation is in the form of a limaçon, r = a – b cos θ.

## What is a Cartesian equation?

: an equation of a curve or surface in which the variables are the Cartesian coordinates of a point on the curve or surface.
