Learned that back on the 82.  You can use a big immediate list and graph
complicated graphs in one equation:
y1={1,2,3,4,5,6,7,8}sin x

Wow, I never thought of that.  Does anyone one else have fun impressing
their entire math class (including the teacher) with all your "useless"
calculator knowledge?
