| <h3>How can I get a left bracket without a right bracket?</h3> |
| <P>Since brackets have a grouping function they must always match and |
| be correctly nested.</P> |
| <P>To get a single bracket without a matching bracket partner you |
| have to escape the bracket with a backslash. For example to get a "[" |
| without a corresponding "]" you should enter <KBD>\[</KBD>.</P> |
| <P>Thus to typeset the interval [3;8) you should enter<KBD> \[3 ";" |
| 8\)</KBD>. The quotation marks around the semicolon ensures that it |
| is not typeset in italic. (You're right, this has nothing to do with |
| brackets!)</P> |
| <P>For scalable brackets it is essential that <KBD>left</KBD> and |
| <KBD>right</KBD> matches, since the content that the brackets |
| encloses must be well defined. |
| </P> |
| <P>In this case you can use the invisible bracket <KBD>none</KBD> to |
| get a single bracket. For example to get a scalable "[" |
| without a corresponding "]" you should enter <KBD>left [ |
| ... right none</KBD>.</P> |
| <P>Thus to typeset |
| <IMG SRC="001a.gif" NAME="Objekt1" ALIGN="middle" HSPACE=8 WIDTH=59 HEIGHT=43 BORDER=0/>you |
| should enter<KBD> x=left lbrace binom -5 3 right none</KBD>.</P> |
