#### Convert polar to rectangular equation

## 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 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.

## How do you do polar coordinates on a calculator?

Enter the number or expression, then ►Rect . To convert an answer to polar form: Enter the number or expression, then ►Polar . The calculator will display the angle (part of the exponent on e) in radians or degrees according to how you set the mode.

## What is rectangular and polar 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.

## How do you put a polar equation into a calculator?

The radian symbol (r) can be found in the Angle menu. So to enter, for example, the polar form number (240∠75) into the calculator you must enter 240 e^(i 75/1r). The calculator will then display 62.12 + 231.8i corresponding to the polar form number (240∠75).

## What are polar coordinates in math?

In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. Angles in polar notation are generally expressed in either degrees or radians (2π rad being equal to 360°).

## 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.
