#1,147 – Converting from Polar Coordinates to Cartesian Coordinates
August 29, 2014 2 Comments
You can represent a two dimensional point as either a cartesian coordinate (X,Y) or a polar coordinate (r,theta). Conversions between these two coordinate systems are shown below.
From polar coordinates to cartesian:
To convert from cartesian coordinates to polar, the following formula works, as long as the X value is positive.
If X is 0 or negative, then the calculation for theta becomes:
