An introduction to HP apps

Much of the functionality of the HP Prime is provided in packages called HP apps. The HP Prime comes with 18 HP apps: 10 dedicated to mathematical topics or tasks, three specialized Solvers, three function Explorers, a spreadsheet, and an app for recording data streamed to the calculator from an external sensing device. You launch an app by first pressing I(which displays the Application Library screen) and tapping on the icon for the app you want.

What each app enables you to do is outlined in the following, where the apps are listed in alphabetical order.

App name	Use this app to:

Advanced	Explore the graphs of symbolic open
Graphing	sentences in x and y. Example:
	x2 + y2 = 64
DataStreamer	Collect real-world data from scientific
	sensors and export it to a statistics app for
	analysis.
Finance	Solve time-value-of-money (TVM) problems
	and amortization problems.
Function	Explore real-valued, rectangular functions
	of y in terms of x. Example:
	y = 2x2 + 3x + 5
Geometry	Explore geometric constructions and
	perform geometric calculations.
Inference	Explore confidence intervals and
	hypothesis tests based on the Normal and
	Student’s t-distributions.
Linear Explorer	Explore the properties of linear equations
	and test your knowledge.
