Breaking long lines in equations

[Peter Percival]

How do I get a long line in

\begin{equation}
...
\end{equation}

to break sensibly?

Not at all. Use equnarray (or one of its improved successors) and the
examples from its documentation.

Don't use eqnarray.

Nooooo! Avoid eqnarray!

What about my "or one of its improved successors" do you two find so
offensive? Eqnarray is the minimal solution to solve the problem posed.

Improvements are possible and indeed desirable, but require extra
packages like amsmath that may conceivably clash with something else. I
wanted to start with the simplest, most basic and most general solution
for the problem at hand.

The main point here is, "For more than one line use a multiline
environment, a single line one won't work." Details and fine points go
on top.

Neither of use complained about the "one of its improved
successors".

eqnarray is the *bad* solution to solve the problem. Didn't you read
the article Uwe linked too?

If you want to a minimal solution without amsmath, then use a
handcrafted array.

No you ignored and disregarded it, which was my point.

I did and found this:

One problem with the align environment is it appears that the pause
command in Beamer does not work in align as it does in eqnarray. This
may seem minor, but it’s important in my lectures

Bob,
Beamer’s pause doesn’t actually work inside any amsmath environment,
“since these do really wicked things” according to the Beamer manual
--------------------------------------------------------------

I feel vindicated in beginning with the simplest and most reliable basic
solution to the primary problem. Noone ever claimed it to be perfect or
not needing improvement. In fact I said so in my first post.

Sure. Like always on usenet I removed the parts I didn't want to
comment. You recommended eqnarray and with this part (and only this)
I disagreed.

The fact that align has its problems too doesn't make eqnarray
better. And if the OP needs a solution working also in beamer he
could read documentation. It contains work-arounds for align. And
one can always use a handcrafted array here too.

Nooooo! Why on earth is this resurfaced over and over again? Avoid
eqnarray!

Sensible line breaking in displayed equations still requires human
brainpower. It cannot be automated in a satisfactory manner, IMO.

Check out the 'amsmath' package and its various environments for
multiline equations, like {multline}, {align}, {gather}, and {split}.

There's also the 'mathtools' package which provides interesting
extensions to 'amsmath', e.g. the {multlined} environment.

Thank you for all replies.

"requires human brainpower", how shocking! What are computers for? :-)

In connection with this problem, in Knuth's 'Computers and typesetting /
A The TeXbook' there is mention of \eqalign (p190f). Does this no
longer exist?

It is still there in plain TeX but not defined in LaTeX.
