HP Solver apps
Solver app name Purpose
Finance Solve time-value-of-money (TVM) and amortization problems
Linear Solver Solve 2×2 and 3×3 systems of linear equations
Triangle Solver Solve problems involving the lengths of sides, and the measures of angles, in triangles
Three apps are specifically designed to help you explore the relationships between the values of the parameters in a function
and the shape of the graph of the function. See the following table.
Table 2-3
HP Explorer apps
Explorer app name Purpose
Linear Explorer Explore the relationship between the shape of the graph and values of the parameters in linear
functions
Quadratic Explorer Explore the relationship between the shape of the graph and values of the parameters in quadratic
functions
Trig Explorer Explore the relationship between the shape of the graph and values of the parameters in sinusoidal
functions

Data persistence

When you work with an app, you enter data of one sort or another, such as definitions of functions, window settings, and
preferences. The app records all this data and automatically saves it for you. If you leave the app and come back to it later,
all that data is still there. In fact, you can save an instance of the app with a new name and keep the original version for
another purpose. The new version, under the new name, contains all the data from the source app. (This is explained in
"Creating customized apps" on page 46.)
