A vector can be represented by its rectangular coordinates x and y or by its polar coordinates r and . Theta is measured in radians. The relationship between them is given by the equations:

 A vector can be represented by its rectangular coordinates x and y or by its polar coordinates r and Theta is measured in radians. The relationship between them is given by the equations:

Assign values for the polar coordinates to variables r and theta. Then, using these values, assign the corresponding rectangular coordinates to variables x and y.
