EQUATION
This section is an overview of the EQUATION Icon. To select this icon, highlight it and
press
l or press f.
The initial Equation Editor screen has three modes to choose from, Simultaneous,
Polynomial, and Solver; this section will give an overview of each mode.
The Simultaneous mode allows you to solve simultaneous linear equations with two to six
unknowns
.
1.
Solve the following system of equations:
7zy4x5
1z3y6x
1z2yx4
Press
q to select the Simultaneous mode and press wfor three unknowns. The
calculator will display a matrix where the coefficients and constants can be entered
in to as long as each equation is in standard form. To enter this system of equations
(already in standard form) input the following:
4 l 1 l n 2 l n 1 l
1 l 6 l 3 l 1 l
n 5 l 4 l 1 l n 7 l
There are four options at the bottom of
the screen, press
q(SOLV). The solution
to this system is (1, -1, 2).
