# Convert Polar to Rectangular Coordinates - Calculator

Convert polar to rectangular two dimensional coordinates using a calculator.

__Polar and Rectangular Coordinates__

The relationships between rectangular coordinates (x , y) and polar coordinates (R , t), using the figure below, are as follows:
**y = R sin t ** and
**x = R cos t**

**R**^{2} = x^{2} + y^{2} and ** tan t = y / x**

where the quadrant of angle t is determined by the signs of x and y.

An html 5 applet is used to calculate x and y knowing R and t. Angle t may be in degrees or radians.

__Use Calculator to Convert Polar to Rectangular Coordinates__

1 - Enter angle t then R (positive). Depending on whether t is in degrees or radians, press the button "Convert" that is in the same row.
