Overlaying Functions on a Graph
On the TI-83 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.
