A Syntax and Input

Rectangular-to-Polar Coordinate Conversion (Pol)Pol(x, y)x: Rectangular coordinate x-valuey: Rectangular coordinate y-valuePolar-to-Rectangular Coordinate Conversion (Rec)Rec(r, Ƨ)r: Polar coordinate r-valueƧ: Polar coordinate Ƨ-value

Example 1: To convert the rectangular coordinates ('2, '2 ) to polar coordinates

ANotes

•These functions can be used in the COMP, SD, and REG Modes.•Calculation results show the first r value or x value only.

•The r-value (or x-value) produced by the calculation is assigned to variable X, while the Ƨ-value (or y-value) is assigned to variable Y (page 22). To view the Ƨ-value (or y-value), display the value assigned to variable Y, as shown in the example.

•The values obtained for Ƨ when converting from rectangular coordinates to polar coordinates is within the range –180°< Ƨ < 180°.

•When executing a coordinate conversion function inside of a calculation expression, the calculation is performed using the first value produced by the conversion (r-value or x- value).

Example: Pol ('2, '2 ) + 5 = 2 + 5 = 7
