#### Polar equation to cartesian equation calculator

## How do you convert polar equation to Cartesian equation?

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

## 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.

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

## What is Cartesian equation of a line?

The cartesian equation for a straight line is y = mx + c, where m represents the gradient of the line, and c is the point where the line crosses the y-axis. A vector equation for a line similarly needs 2 pieces of information: A point on the line. The direction of the line .

## What is Cartesian equation of curve?

A cartesian equation for a curve is an equation in terms of x and y only. Definition. Parametric equations for a curve give both x and y as functions of a third variable (usually t).

## What is a Cartesian equation of a circle?

Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)^{2} + (y − b)^{2} = r^{2} where a and b are the coordinates of the center (a, b) and r is the radius.

## What is polar and Cartesian coordinates?

Polar Coordinates. Main Concept. The Cartesian coordinate system is a two-dimensional coordinate system using a rectilinear grid: • The x and y coordinates of a point measure the respective distances from the point to a pair of perpendicular lines in the plane called the coordinate axes, which meet at the origin.
