Numerical Equation Solver - Casio Fx-CG20 User Manual

Numerical Equation Solver

The "Equation"- application is used for the numerical solving of
equations. Three types of equations can be solved:
– ( Uniquely solvable ) Linear Equation systems with 2-5 Unknowns.
– Polynomial equations 2-6 Order.
– General Equations ( Solver )
Selecting the Type of Equation
Once the "Equations"- application is opened, a selection bar will
appear. Select the Equation type with [ F1 ] - [ F3 ]
Linear Equation system ( Simultaneous )
Before values are entered, the numbers of the unknowns
must be entered.
The input pattern is displayed at the top of the screen.
Note: The "Equations"- application computes the unique solution,
detachable LGS. To determine the over or under certain LGS,
the Matrix notation and Rref-command is required. ( vgl. S.17 )
Polynomial Equations
2-6 Grades from the polynomial equations can be solved. The input
pattern is displayed at the top of the screen.
General Equations ( solver )
Input an equation ( equality sign: [ SHIFT ] [ . ]) and enter the
start value for the calculation. Solve the equation by pressing [ F6 ]
( SOLVE )
