#### Cartesian equation to polar equation

## How do you convert polar to Cartesian equation?

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

## How do you rewrite a Cartesian equation as a polar equation?

Rewrite the polar equation r=sin(2θ) in Cartesian form. r=sin(2θ)Use the double angle identity for sine. r=2sinθcosθUse cosθ=xr and sinθ=yr. r=2(xr)(yr) Simplify.

## What is 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.

## What is a 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.

## 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.

## 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.

## How do you convert a parameter to Cartesian equation?

A cartesian equation of a curve is simply finding the single equation of this curve in a standard form where xs and ys are the only variables. To find this equation, you need to solve the parametric equations simultaneously: If y = 4t, then divide both sides by 4 to find (1/4)y = t.
