## How do you calculate polar and rectangular?

In general, to convert between polar and rectangular coordinates use the following rules: x = r cos(θ) y = r sin(θ) r = (x2 + y2)1/2.

## 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 equation?

Polar Equations A polar equation is any equation that describes a relation between r r r and θ theta θ, where r r r represents the distance from the pole (origin) to a point on a curve, and θ theta θ represents the counterclockwise angle made by a point on a curve, the pole, and the positive x x x-axis.

## 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.

## How do you convert rectangular to polar form?

To convert from Cartesian Coordinates (x,y) to Polar Coordinates (r,θ):r = √ ( x2 + y2 )θ = tan1 ( y / x )

## Are Cartesian and rectangular coordinates the same?

The Cartesian coordinates (also called rectangular coordinates) of a point are a pair of numbers (in two-dimensions) or a triplet of numbers (in three-dimensions) that specified signed distances from the coordinate axis.

## How do polar coordinates work?

The polar coordinates of a point describe its position in terms of a distance from a fixed point (the origin) and an angle measured from a fixed direction which, interestingly, is not “north” (or up on a page) but “east” (to the right). That is in the direction Ox on Cartesian axes.

## How do you find rectangular coordinates?

How to: Given polar coordinates, convert to rectangular coordinates.Given the polar coordinate (r,θ), write x=rcosθ and y=rsinθ.Evaluate cosθ and sinθ.Multiply cosθ by r to find the x-coordinate of the rectangular form.Multiply sinθ by r to find the y-coordinate of the rectangular form.
