7-4 Solve Calculations

You can determine the value of any variable you are using without having to solve

the equation.

Input the equation, and a table of variables appears on the display. Use the table

to assign values to variables and then execute the calculation to obtain a solution

and display the value of the unknown variable.

k k k k k Entering the Solve Calculation Mode

While in the Equation Mode, press 3 (SOLV). The Solve input screen appears.

Input the expression. You can input numbers, alpha-characters, and operation

symbols. If you do not input an equals sign, the calculator assumes that the

expression is to the left of the equals sign and there is a zero to the right. To

specify a value other than zero to the right of the equals sign, you must input the

equals sign and the value.

u u u u u To perform solve calculations

The following formula expresses the relationship between height H, initial velocity

V, time T, and gravitational acceleration G of a free falling object.

1. Press 2 (DEL) 1 (YES) to clear any previously input equations.

2. Input the equation.

• You cannot use the variable table in the Program Mode. When you want to use

the Solve calculation function in the Program Mode, you have to use program

commands to assign values to variables.

Example

To calculate initial velocity of an object thrown into the air and

taking a time of 2 seconds to reach a height of 14 meters, when

gravitational acceleration is 9.8 m/s

H = VT – –– GT

aH!=aVaT-(b/c)aGaTx
