• To change a coefficient value you already have input, move the cursor
to the appropriate cell, input the new value, and then press =.
• Pressing A will clear all of the coefficients to zero.
Note: The following operations are not supported by the Coefficient Editor:
m, 1m(M–), 1t(STO). Pol, Rec, ÷R, and multi-statements also
cannot be input with the Coefficient 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
A.
Note: Values cannot be converted to engineering notation on the solution
screen.
Changing the Inequality Type
Press Nc1(INEQ) and then select an inequality type from the menu
that appears. Changing the inequality type causes the values of all Coefficient
Editor coefficients to change to zero.
