On the TI
-
83, you can graph one or more new functions
without replotting existing functions. For example, store
sin(X) to Y
1
in the
Y=
editor and press
s
. Then store
cos(X) to Y
2
and press
s
again. The function Y
2
is
graphed on top of
Y
1
, the original function.
If you enter a list (Chapter 11) as an element in an
expression, the TI
-
83 plots the function for each value in
the list, thereby graphing a family of curves. In
Simul
graphing-order mode, it graphs all functions sequentially
for the first element in each list, and then for the second,
and so on.
{2,4,6}sin(X) graphs three functions: 2 sin(X), 4 sin(X), and
6 sin(X).
{2,4,6}sin({1,2,3}X) graphs 2 sin(X), 4 sin(2X), and 6 sin(3X).
Note:
When using more than one list, the lists must have the same
dimensions.
