Notice that if you enter
y = 6 - x
and y = - Y1 for Y2, you will
not get the graph of a circle
because the " " does not go
with the "-2".
Notice that "=" for Y1 is no
longer darkened. You now
have the top portion and the
bottom portion of the circle
in Y2 and Y3.
Wait until the graph is dis-
played after each operation.
(It takes few seconds to
graph)
