The next neqn operation is called "sqrt" - it makes
|
|
square root signs over things, like this:
|
|
.EQ
|
|
sqrt a+b
|
|
.EN
|
|
(They don't look very good on a terminal, unfortunately.)
|
|
This one is very easy - to print the line above, you
|
|
say
|
|
.EQ
|
|
sqrt a+b
|
|
.EN
|
|
The "sqrt" operates on the first thing it finds
|
|
so if you want something more complicated, like
|
|
.EQ
|
|
sqrt {pi +1}
|
|
.EN
|
|
you have to use braces to enclose the entire
|
|
thing. This one was printed with
|
|
.EQ
|
|
sqrt {pi +1}
|
|
.EN
|
|
And that's all there is to sqrt.
|
|
|
|
Modify "Example" so it looks like this, then type "ready".
