3. Use the Coefficient Editor that appears to input coefficient values.
• To solve 2x
2
+ x - 3 = 0, for example, press in step 2, and then
input the following for the coefficients (a = 2, b = 1, c = -3): 2
1
3 .
• 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.
Important!
•
The following operations are not supported by the Coefficient Editor: ,
(M-), (STO). Pol, Rec, ÷R, and multi-statements also cannot be
input with the Coefficient Editor.
4. After all the values are the way you want, press
.
• This will display a solution. Each press of will display another
solution. Pressing while the final solution is displayed will return to
the Coefficient Editor.
• You can scroll between the solutions using the and keys.
•
To return to the Coefficient Editor while any solution is displayed,
press .
Note
• Even if Natural Display is selected, the solutions of simultaneous linear equations are
not displayed using any form that includes √ .
• Values cannot be converted to engineering notation on the solution screen.
• A message appears to let you know when there is no solution or when there are
infinite solutions. Pressing or will return to the Coefficient Editor.
Changing the Current Equation Type Setting
Press
(EQN) and then select an equation type from the menu that
appears. Changing the equation type causes the values of all Coefficient
Editor coefficients to change to zero.
