• To change a coefficient value you already have input, move the cursor
to the appropriate cell, input the new value, and then press .
• Pressing will clear all of the coefficients to zero.
Note:The following operations are not supported by the Coef
ficient
Editor:
, (M-), (STO). Pol, Rec, and multi-statements
also cannot be input with the Coef
ficient Editor.
5. After all the values are the way you want, press
.
• This will display the solutions.
• To return to the Coefficient Editor while the solutions are displayed,
press .
Note
• Values cannot be converted to engineering notation on the solution screen.
Changing the Inequality T
ype
Press
(INEQ) and then select an inequality type from the menu
that appears. Changing the inequality type causes the values of all
Coef
ficient Editor coefficients to change to zero.
