HP 30S Calculator - Converting Coordinates between Rectangular and Polar

Introduction
Entering an ordered pair on a two-dimensional graph (including imaginary numbers) can be done in one of two ways.
  • Rectangular or Cartesian coordinates
  • Polar or Cylindrical coordinates
The instructions below explain how to enter Ordered Pairs using both rectangular and polar notations. The instructions will demonstrate how to convert between the two notations.
  note:
Decimal number format is set at Fixed 2 decimal placement.
Examples
  note:
The word THETA represents the Theta symbol.
Example 1
Change (3,4) Rectangular coordinates to Polar with the Angle Measure in Degrees.
  1. Press the 2nd key, then R<>P, R ->Pr is underlined, then press ENTER.
  2. Type in 3 then press the 2nd key, press (,) comma key, type in 4, press ENTER. The display will show 5.00 this is the radius coordinate.
  3. Press the 2ndkey, R<>P key, arrow once to the right, underlining R->PTHETA, then press ENTER.
  4. Type in 3 then press the 2nd key, press (,) comma key, type in 4, press ENTER. The display will show 36.87, this is the theta angle coordinate.
Example 2
Change (17, 61.93) Polar coordinates to Rectangular with the Angle Measure in Degrees.
  1. Press the 2nd key, the R<> P, arrow twice to the right or until P ->Rx is underlined, then press ENTER.
  2. Type in 17, press the 2nd key, press (,) comma key, type in 61.93, then press ENTER. The calculator will display 8.00. This is the x coordinate.
  3. Press the 2nd key, the R<> P key, arrow once to the left or until P ->Ry is underlined, then press ENTER.
  4. Type in 17, press the 2nd key, press (,) comma key, type in 61.93, then press ENTER. The calculator will display 15.00. This is the y coordinate.
      note:
    Any angle arguments are dependent on the current angle format, when in degrees mode, the polar angle will be expressed as degrees.
