Function Memory and Graph Memory
Function memory lets you store functions for later recall when you need them.
With graph memory, you can store graphs in memory. Press the
J
key and then input the
name of the graph.
Example To differentiate f

Eqn Memory
When a calculation result is an equation or inequality, its formula number is displayed in the
formula number area, and the equation is stored in Eqn memory.*
1
Stored equations can be
recalled with the eqn command, rclEqn command or rclAllEqn command.

Using the CAS (Computer Algebra System) Mode
*
1
Up to 99 formulas can be stored in Eqn
memory.
The error message “Memory ERROR” when
you try to store an equation when there are
already 99 equations in Eqn memory. When
this happens, execute the ALLEQU (Delete
All Equations) from the CLR menu.
