Entering an ordered pair on a two dimensional graph (including imaginary numbers) can be done in either of two ways.
The instructions in this document explain how to enter ordered pairs using both rectangular and polar notations. The instructions will demonstrate how to convert between the two notations. In addition, instructions on adding and subtracting the ordered pairs are included.
Decimal number format is set at Fixed 2 decimal placement.
Ordered pairs are set between parentheses. The difference between entering a rectangular coordinate and a polar coordinate is that rectangular coordinates are separated by a comma, while polar or cylindrical coordinates are separated by an angle symbol.
