304 Programming
DoInference Calculate confidence interval or test hypothesis. Performs
the same calculations as pressing in the Inference
app's Numeric view and stores the results in the
appropriate Inference app results variables.
DoInference()
Sequence app
functions
The Sequence app has a single function for defining a
sequence and storing it into one of the Sequence app
Symbolic variables U0-U9.
RECURSE Recursion. Provides a method for defining a sequence
without using the Symbolic view of the Sequence app. Un
is one of the Sequence app Symbolic view variables U0-
U9, nthterm is an expression in N, Un(N-1), and/or Un(N-
2), and term1 and term2 are the first two terms of the
sequence. If nthterm is an expression only in N, then
term1 and term2 are optional.
RECURSE(Un, nthterm [, term1, term2])
Examples:
RECURSE(U1, N) defines the sequence U1 to be the
sequence of counting numbers.
RECURSE(U2, U2(N-1)*N, 1) defines U2 to create a
factorial-calculating sequence. U2(5), for example, will
return 120.
RECURSE(U3, U3(N-2)+U3(N-1), 1, 1) defines U3 to
be the Fibonacci sequence.
Finance app
functions
The Finance app has a single function that returns the
same results as pressing in the Finance app's
Numeric view.
DoFinance Calculate TVM results. Solves a TVM problem for the
variable TVMVar. The variable must be one of the
Finance app's Numeric view variables. Performs the
same calculation as pressing in the Finance app
Numeric view with TVMVar highlighted.
DoFinance(TVMVar)
Example:
DoFinance(FV) returns the future value of an investment
in the same way as pressing in the Finance app
Numeric view with FV highlighted.
