Math behind Converting Polar to Rectangular Coordinates
Converting from Polar to Rectangular (also called Cartesian) coordinates is easy to do. Refer to this diagram:
Variables used in polar to rectangular coordinate conversions...
The variables used in polar to rectangular coordinate conversion are:
x: The XAxis coordinate
y: The YAxis coordinate
r: The radius or distance on the polar vector
Theta (Greek character): The angle from the XAxis in a counterclockwise direction
Equation to Convert Polar to Rectangular Coordinates
Given r and Theta, we can find x and y to convert from Polar to Rectangular coordinates as follows:
x = r Cos( Theta )
y = r Sin( Theta )
Equation to Convert Rectangular to Polar Coordinates
If we know x and y, we can find r and Theta to convert from Rectangular to Polar coodinates as follows:
r = SQRT( x * x + y * y )
Theta = arctan( y / x )
