The next construction we're going to look at
|
|
is one for putting things above and below other
|
|
things, in a rather specialized way.
|
|
For example, if you want something like
|
|
.EQ
|
|
sum from i to j
|
|
.EN
|
|
you type
|
|
.EQ
|
|
sum from i to j
|
|
.EN
|
|
The words "from" and "to" are more magic, like
|
|
sub or sup or over. The "from" part is centered
|
|
under the main piece; the "to" part is centered
|
|
above it.
|
|
As a warmup, modify "Example" so it produces
|
|
output that looks like the following, then type
|
|
ready.

Let $Q( pi )$ be $sum from {i= pi sub 1} to {i= pi sub 2} x sub i$.
