Chapter 3: Scientific Calculations

Solver Function

This function enables you to find any variable in an equation.

Entering and solving an equation

The solver function is used as follows.

1.Press b0to enter the NORMAL mode.

2.Enter both sides of an equation, using ‘=’ and variable names.

3.Press I5.

4.Enter the value of the known variables.

5.Move the cursor (display) to the unknown variables.

6.Press @h.

•The solver function can find any variable anywhere in an equation. It can even find variables that appear several times in an equation.

•You can use both global and local variables in your equation. (See page 58.)

NORMAL MODE 0.

TŒ=(4π©GM)R_

Equation entering display

•Using the solver function will cause variables memory to be overwritten with new values.

•To exit the solver function, press j.

Changing the value of variables and editing an equation

When you are in the solution display, press eto return to the display for entering values of variables, then return to the equation display in the NORMAL mode by pressing j.
