- caren levine (comp.text.tex, october 30) reports that she is getting
- error messages when she tries to break a long formula in display mode.
-
- the answer is simple.
-
- the display contains the terms \left{ and \right} and the length of
- the formula requires that the left and right members of the pair be
- on different lines.
-
- tex requires that \left...\right be matched within a single formula
- (texbook, p. 148). the catch here is that tex considers different
- lines of a multi-line display each to be a separate formula. so
- the \left{ in the first line must be matched by \right. in the same
- line, and similarly with the \right} in the third line.
-
- see the texbook, p. 196, first "dangerous bend" paragraph, for a
- specific example. (note that suitable \phantom's can be used
- instead of the \bigg shown there to assure that the sizes of the
- delimiters come out the same.)
