EQN calculation mode (calculating equations)
In the EQN mode it is possible to solve systems of linear equations, quadratic
and cubic equations.
A menu with 4 types of equations appears if [MODE/SET UP][5] is pressed,
then choose the EQN mode.
EQN Menu Equation
1:
A system of linear equations with two unknown variables.
2: A system of linear equations with three unknown variables.
3: Quadratic equations.
4: Cubic equations.
After the equation type is selected, enter the value of every coefcient (a1,
b1 etc.) and press
[=] . Maximum 6 digits of the number are displayed in a
respective cell but a complete number is used for calculation.
When all the coefcients have been entered, press [=] to solve the system.
Every time the [=] key is pressed, the unknown variable is displayed that is a
solution to the equation.
Press [=] again to display the table for entering the coefcients again.
To change the already entered coefcient, move the cursor to a respective cell
with a coefcient, enter a new value and press [=] . To delete all coefcients,
press [AC] .
Press [AC] during the display of the solution to the system to return to the table
for entering the coefcients.
MATRIX calculation mode
Matrices may be stored in matrix memory under the names of „MatA“, „MatB“
and „MatC“. Results of the calculations with matrices are stored in a special
memory of matrix calculation results that is called “MatAns”.
To set the calculator in the “MATRIX” mode: press [MODE/SET UP] and then [6] .
Creating the matrix:
• Press [2ND][4] (MATRIX) [1] (Dim).
• Press [1] or [2] or [3] to dene the matrix name.
