# Polar to Rectangular Calculator

Rectangular coordinates, or cartesian coordinates, come in the form (x, y), points are identified by their distances from the x and y axes. Polar coordinates, on the other hand, come in the form (r, θ), points are identified by their angle on the unit circle and their distance from the origin.

## How to Find Polar to Rectangular Calculator?

Polar coordinates are expressed as (r, θ) while rectangular coordinates are expressed as (x,y)

Converting polar to rectangular coordinates means expressing the polar coordinates in the form of rectangular coordinates.

The formula's for converting polar coordinates to rectangular coordinates:

**x = rcosθ, y = rsinθ**

Where (r, θ) are polar coordinates and (x, y) are rectangular coordinates

**Solved Examples on Polar to Rectangular Calculator**

**Example 1:**

Convert polar coordinates (5, 45°) into rectangular coordinates.

**Solution:**

Given: r = 5, θ = 45°

To convert polar to rectangular coordinates,

x = rcosθ

= 5cos45°

= 5 / **√**2

x = 3.536

y = rsinθ

= 5 sin45°

= 5 / **√**2

y = 3.536

Therefore, rectangular coordinates (x, y) = (3.536, 3.536)

**Example 2:**

Convert polar coordinates (7, 30°) into rectangular coordinates.

**Solution:**

Given: r = 7, θ = 30°

To convert polar to rectangular coordinates,

x = rcosθ

= 7cos30°

= 7(**√**3/2)

x = 6.06

y = rsinθ

= 7 sin30°

= 7 / 2

y = 3.5

Therefore, rectangular coordinates (x, y) = (6.06, 3.5)

**Example 3:**

Convert polar coordinates (4, 60°) into rectangular coordinates.

**Solution:**

Given: r = 4, θ = 60°

To convert polar to rectangular coordinates,

x = rcosθ

= 4cos60°

= 4 / 2

x = 2

y = rsinθ

= 4 sin30°

= 4(**√**3/2)

y = 3.465

Therefore, rectangular coordinates (x, y) = (2, 3.465)

Similarly, you can use the calculator to convert polar to rectangular coordinates for the following:

- Convert polar coordinates (11, 60) into rectangular coordinates
- Convert polar coordinates (7, 30) into rectangular coordinates
