HP Prime Graphing NW280AAABA manual Linear Solver, Equations

App name	Use this app to: (Cont.)
Linear Solver	Find solutions to sets of two or three linear
	equations.
Parametric	Explore parametric functions of x and y in
	terms of t. Example: x = cos (t) and
	y = sin(t).
Polar	Explore polar functions of r in terms of an
	angle θ. Example: r = 2 cos(4θ)
Quadratic	Explore the properties of quadratic
Explorer	equations and test your knowledge.
Sequence	Explore sequence functions, where U is
	defined in terms of n, or in terms of
	previous terms in the same or another
	sequence, such as Un – 1 and Un – 2 .
	Example: U1 = 0 , U2 = 1 and
	Un = Un – 2 + Un – 1
Solve	Explore equations in one or more real-
	valued variables, and systems of equations.
	Example: x + 1 = x2 – x – 2
Spreadsheet	To solve problems or represent data best
	suited to a spreadsheet.
Statistics 1Var	Calculate one-variable statistical data (x)
Statistics 2Var	Calculate two-variable statistical data
	(x and y)
Triangle Solver	Find the unknown values for the lengths
	and angles of triangles.
Trig Explorer	Explore the properties of sinusoidal
	equations and test your knowledge.

As you use an app to explore a lesson or solve a problem, you add data and definitions in one or more of the app’s views. All this information is automatically saved in the app. You can come back to the app at any time and all the information is still there. You can also save a version of the app with a name you give it and then use the original app for another problem or purpose. See “Creating an app” on page 107 for more information about customizing and saving apps.
