Solve Calculations - Casio CFX-9970G Manual

7-4 Solve Calculations

You can determine the value of any variable you are using without going through
the trouble of solving an 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.

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
