– For a Function
definition, enter
an expression to
define F(X). The
only independent
variable in the
expression is X.
– For a
Parametric
definition, enter
a pair of
expressions to
define X(T) and
Y(T). The only
independent variable in the expressions is T.
– For a Polar
definition, enter
an expression to
define R(θ). The
only independent
variable in the
expression is θ.
– For a Sequence
definition, either
enter the first term,
or the first and
second terms, for U
(U1, or...U9, or
U0). Then define
the nth term of the sequence in terms of N or of
the prior terms, U(N–1) and/or U(N–2). The
expressions should produce real-valued
sequences with integer domains. Or define the
nth term as a non-recursive expression in terms of
n only. In this case, the calculator inserts the first
two terms based on the expression that you
define.
– Note: You will have to enter the second term if the
hp40gs is unable to calculate it automatically.
Typically if Ux(N) depends on Ux(N–2) then you
must enter Ux(2).
