F. THE TERRORS OF ERRORSF.2 LATEX ERRORSLaTeX errors introduce themselves differently from those that TeX finds. For example, ifyou ever happended to use the \caption command outside a float, like:\caption{Naked}you would get the message:! LaTeX Error: \caption outside float.See the LaTeX manual or LaTeX Companion for explanation.Type H for immediate help....l.624 \caption{Naked}?If you then typed H in response you would get the following helpful message:You’re in trouble here. Try typing to proceed.If that doesn’t work, type X to quit.?The majority of LaTeX’s help messages follow this formula, so I have not noted them inthe alphabetical listing below.\< in mid lineA \< appears in the middle of a line in a tabbing environment; it should only comeat the start of a line.... allowed only in math modeYou have tried to use a math command in a non-math mode.Bad \line or \vector argumentA \line or \vector has a negative length argument or the slope is not within theallowed range.Bad math environment delimeterIf in math mode there is a start math mode command like \( or \[ or if in LR or paragraphmode there is an end math mode command like \)or \]. The basic problem isunmatched math mode delimeters or unbalanced braces.\begin{...} ended by \end{...}The name of the \begin argument is not the same as the name of the \end argument.This could be caused by a typo or a missing \end.Can only be used in the preambleSome commands can only be used in the preamble, such as \usepackage, but therewas one of these after the \begin{document}.458
