Hypertext Help with LaTeX



Prints eqn in display math style, but pretends that it has zero width. It is typicaly used within an Eqnarray environment for displaying long equations that require multiple lines.

A typical use might be

    \lefteqn{\int_0^\infty some expression =} \\
    & & some terms \\
    & & \mbox{} + more terms

Note that the empty \mbox{} is so LaTeX knows that the following + is a binary operator, and is not attached to the first of the "more terms" as a unary operator.
