Important!

• This calculator may abort calculation part way through when an overflow occurs part way

through the calculation when calculated solutions cause the solution curve to extend into

a discontinuous region, when a calculated value is clearly false, etc.

• The following steps are recommended when the calculator aborts a calculation as

described above.

1. If you are able to determine beforehand the point where the solution curve overflows,

stop the calculation before the point is reached.

2. If you are able to determine beforehand the point where the solution curve extends into

a discontinuous region, stop the calculation before the point is reached.

3. In other cases, reduce the size of the calculation range and the value of h (step size)

and try again.

4. When you need to perform a calculation using a very wide calculation range, store

intermediate results in a list and perform a new calculation starting from step 3 using

the stored results as initial values. You can repeat this step multiple times, if necessary.

k SET UP Items

G-Mem {G-Mem 20}/{1 – 20} ...... Specifies a memory location {G-Mem No.} for storage of

the latest graph functions.

Note the following regarding SET UP screen settings whenever using the DIFF EQ Mode.

The DIFF EQ Mode temporarily stores data into Graph Memory whenever a differential

equation calculation is performed. Before the calculation, DIFF EQ stores the latest graph

functions into the currently specified Graph Memory (G-Mem) location. After the calculation,

it recalls the graph functions from the specified G-Mem location, without deleting the G-Mem

data. Because of this, you should specify the G-Mem location (number) where the DIFF EQ

Mode stores the graph functions.
