Linear Solver aplet
About the Linear Solver apletThe Linear Solver aplet allows you to solve a set of linear equations. The set can contain two or three linear equations.
In a
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 hp40gs 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.
Getting started with the Linear Solver apletOpen the Linear Solver aplet
Choose the equation set
The following example defines a set of three equations and then solves for the unknown variables.
1. Open the Linear Sequence aplet.
Select Linear
Solver
The Linear Equation
Solver opens.
2.If the last time you used the Linear Solver aplet you solved for two equations, the two- equation input form is displayed (as in the
