Linear Solver aplet
The Linear Solver aplet allows you to solve a set of Linear
Equations. The set can contain two or three linear
equations.
In a two-equation set, each equation must be in the form
ax
+
by
=
k
. In a three-equation set, each equation must
ax
be in the form
You provide values for a, b, and k (and c in three-
equation sets) for each equation, and the Linear Solver
aplet will attempt to solve for x and y (and z in three-
equation sets).
The hp39gs will alert you if no solution can be found, or
if there is an infinite number of solutions.
Note that the Linear Solver aplet only has a numeric view.
