# Polar to Rectangular Online Calculator

Below is an interactive calculator that allows you to easily convert complex numbers in polar form to rectangular form, and vice-versa. There's also a graph which shows you the meaning of what you've found.

For background information on what's going on, and more explanation, see the previous pages,

## Interactive Graph - Convert polar to rectangular and vice-versa

In the following graph, the **real** axis is horizontal, and the **imaginary** axis is vertical, as usual.

Point P represents a complex number.

### Things to do

Choose whether your angles will be in degrees or radians first.

Enter your values for either radius and angle, or real value and imaginary value and click "Calculate" to see the equivalent result (or you can press <Enter> on your keyboard).

You can also drag point P to change the radius of the circle, and/or the angle to your desired values.

You can zoom the graph in or out using the navigation icons at the bottom of the graph, and pan left-right, up-down by holding down the <Shift> key while dragging the graph.

Go back to the examples on the Polar Form page and try them here in the calculator, and compare the results.
