uTo delete a function

Example To delete the contents of function memory number 1

K6(g)6(g)3(FMEM)A

1(STO) 1(f1)

•Executing the store operation while the display is blank deletes the function in the function memory you specify.

uTo use stored functions

Once you store a function in memory, you can recall it and use it for a calculation. This feature is very useful for quick and easy input of functions when programming or graphing.

Example To store x3 + 1, x2 + x into function memory, and then graph: y = x3 + x2 + x + 1

Use the following View Window parameters.

Xmin

= –4

Ymin

= –10

Xmax

=

4

Ymax

=

10

Xscale =

1

Yscale =

1
