8-10 Storing Functions in Memory
You can store up to 30 functions and ‘expressions in memory for later recall, editing, or
graphing. Rectangular coordinate, polar coordinate, and parametric functions, as well as
inequalities can all be stored in memory. Note that the total amount of memory used for
storage of functions cannot exceed 127 bytes.
