Coordinate Conversion

You can convert from polar to rectangular and from rectangular to polar. The calculation
results are automatically assigned to variables E and F. Note: For both examples, be
sure you are in degree mode.
To convert polar coordinates (r, θ) to rectangular coordinates (x, y).
Example: To convert ( r = 2, θ = 60) to rectangular coordinates:
Press [SHIFT] [REC] [2] [ , ] [60] [ ) ] [=]
