On the TI-84 Plus, you can graph one or more new functions without replotting existing
functions. For example, store
sin(X) to Y1 in the Y= editor and press s. Then store
cos(X) to Y2 and press s again. The function Y2 is graphed on top of Y1, the
original function.

If you enter a list (Chapter 11) as an element in an expression, the TI-84 Plus 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.
