138 Functions and commands

Plot

Function Used to define a function graph in the Symbolic view of the

Geometry app. Plots the graph of an expression written in

terms of the independent variable x. Note that the variable is

lowercase.

plotfunc(Expr)

Example:

plotfunc(3*sin(x)) draws the graph of y=3*sin(x)

Contour Used to define a contour graph in the Symbolic view of the

Geometry app. Given an expression in x and y, as well as a

list of variables and a list of values, plots the contour graph of

the surface z=f(x,y). Specifically, plots the contour lines z1,

z2, etc. defined by the list of values.

Example:

plotcontour(x^2+2*y^2-2, {x, y}, {2, 4,

6}) draws the three contour lines of z=x^2+2*y^2–2 for z=2,

z=4, and z=6.

App menu

Press D to open the

Toolbox menus (one of which

is the App menu). App

functions are used in HP

apps to perform common

calculations. For example, in

the Function app, the Plot

view Fcn menu has a

function called SLOPE that calculates the slope of a given

function at a given point. The SLOPE function can also be

used from the Home view or a program to give the same

results. The app functions described in this section are

grouped by app.
