The **Cartesian to Polar Coordinates** calculator computes the polar coordinates for a vector given in 2D Cartesian coordinates.

**INSTRUCTIONS:** Enter the following:

- (
**x, y**): Vector

**Polar Coordinates (r,θ)**: The calculator returns the magnitude of the vector (r) as a real number, and the polar angle (θ) as degrees. However, these can be automatically converted to compatible units via the pull-down menu.

The formula for Cartesian to Polar coordinates is:

- `r = sqrt(x^2 + y^2)`
- θ = atan2(x,y)

where:

- r = magnitude of the (x,y) vector
- θ = polar angle
- (x,y) = coordinates of (x,y) vector

Polar coordinates are a two-dimensional coordinate system in which a point in the plane is determined by its distance from a reference point and the angle relative to a reference direction.

Here’s how polar coordinates work:

- Reference Point (Pole): The fixed point in the system is called the pole, typically represented as the origin (0, 0) in Cartesian coordinates.
- Radial Distance (r): The distance from the pole to the point in question. It is always a non-negative value (r ≥ 0).
- Angle (θ): The angle measured counterclockwise from the positive x-axis to the line connecting the point to the pole. The angle can be in degrees or radians and can be positive (counterclockwise direction) or negative (clockwise direction).

In polar coordinates, a point is represented as (r,θ), where:

- r is the radial distance.
- θ is the angle.
