Tip:
• In the number table, you can change the value in the currently
highlighted x cell. Changing the x value causes the f(x) and g(x) values
in the same line to be updated accordingly.
• If there is value in the x cell above the currently highlighted x cell,
pressing
or automatically inputs into the highlighted cell the
value equal to the value of the cell above it plus the step value. So
also, pressing automatically inputs the value equal to the value of
the cell above less the step value. The f(x) and g(x) values in the
same line are also updated accordingly.
Note
• The maximum number of rows in the generated number table depends on the setup
menu table setting. Up to 45 rows are supported for the “f(x)” setting, while 30 rows
are supported for the “
f(x),g(x)” setting.
• The number table generation operation causes the contents of variable x to be
changed.
Important!
• Functions input in this mode are deleted whenever the Input/Output settings are
changed in the Table Mode.
Ratio Calculations
The Ratio Mode lets you determine the value of X in the ratio expression
A : B = X : D (or A : B = C : X) when the values of A, B, C and D are
known. The following shows the general procedure for using Ratio.
1. Press
, select the Ratio Mode icon, and then press .
2. On the menu that appears, select (A:B=X:D) or (A:B=C:X).
3. On the Coefficient Editor screen that appears, input up to 10 digits for
each of the required values (A, B, C, D).
• To solve 3 : 8 = X : 12 for X, for example, press in step 1, and
then input the following for the coefficients (A = 3, B = 8, D = 12): 3
8 12 .
