kInputting Coefficients

Use the coefficient editor screen to input the coefficients of an equation. The coefficient editor screen shows input cells for each of the coefficients required by the currently selected equation type.

Simultaneous linear

Cubic equation

equations with two unknowns

 

Rules for Inputting and Editing Coefficients

Data you input is inserted into the cell where the cursor is located. When you register input into a cell, the cursor moves to the next cell to the right.

When simultaneous linear equations with three unknowns or cubic equation is selected as the equation type, the d column will not be visible on the display when the coefficient editor screen is first displayed. The d column will become visible when you move the cursor to it, which causes the screen to shift.

The values and expressions you can input on the coefficient editor screen are the same as those you can input in the COMP Mode with Linear format.

Pressing Awhile inputting data clears your current input.

After inputting data, press =.This registers the value and displays up to six of its digits in the currently selected cell.

To change the contents of a cell, use the cursor keys to move the cursor to the cell and then input the new data.

Initializing All Coefficients to Zero

You can clear all coefficients to zero by pressing the Akey while inputting values on the coefficient editor screen.

Coefficient Editor Screen Input Precautions

Coefficient editor screen precautions are basically the same as those for the STAT editor screen. The only difference is that the first STAT editor screen precaution does not apply in the case of the coefficient editor screen.For details, see “STAT Editor Screen Input Precautions”.

kSolution Display

After inputting and registering values on the coefficient editor screen, press =to display the solution(s) for the equation.

Each press of =displays the next solution, if there is one. Pressing = while the final solution is displayed returns to the coefficient editor screen.
