Getting started
symbolic views of the aplets in the following table. See
"Aplet view configuration" on page 1-18 for further
information.
Aplet Use this aplet to explore:
name
Function Real-valued, rectangular functions y in
terms of x. Example:
Inference Confidence intervals and Hypothesis
tests based on the Normal and
Students-t distributions.
Parametric Parametric relations x and y in terms of
t. Example: x = cos(t) and y = sin(t).
Polar functions r in terms of an angle θ.
Polar
Example:
Sequence Sequence functions U in terms of n, or
in terms of previous terms in the same or
another sequence, such as
U
. Example:
n 2 –
U = U
n n 2 –
Solve Equations in one or more real-valued
variables. Example:
Finance Time Value of Money (TVM)
calculations.
Linear Solutions to sets of two or three linear
Solver equations.
Triangle Unknown values for the lengths and
Solver angles of triangles.
Statistics One-variable (x) or two-variable (x and
y) statistical data.
In addition to these aplets, which can be used in a variety
of applications, the HP 40gs is supplied with two
teaching aplets: Quad Explorer and Trig Explorer. You
cannot modify configuration settings for these aplets.
A great many more teaching aplets can be found at HP's
web site and other web sites created by educators,
together with accompanying documentation, often with
student work sheets. These can be downloaded free of
