ORDERED_PAIR_INDEXING

Returns the value of the OrderedPair at the requested index. Params: default : OrderedPair The input OrderedPair to index. index : int The index of the OrderedPair to return. x_axis : bool Index x axis? If not y is indexed. Returns: out : Scalar The scalar index of the input OrderedPair.

This app uses ordered pair transformation techniques.

First the necessary blocks were added:

• LINSPACE
• SINE
• ORDERED_PAIR_LENGTH
• ORDERED_PAIR_INDEXING
• ORDERED_PAIR_DELETE
• 2x BIG_NUMBER
• TABLE

LINSPACE and SINE created an ordered pair data type (x and y axis pairs). ORDERED_PAIR_LENGTH extracts the length of an ordered pair (this length is viewed with BIG_NUMBER here). ORDERED_PAIR_INDEXING extracts a single value from either the x or y axes (this value is viewed with BIG_NUMBER here). ORDERED_PAIR_DELETE deletes single indexes from both the x or y axes and outputs a new ordered pair (the new ordered pair is viewed with BIG_NUMBER here).

The blocks were connected as shown and the app was run.
