#### \_ (where _ is blank)

• Ordinary whitespace to be used after a dot not denoting the end of a sentence
• After commands without parameters use \~ (tilde) instead in order to avoid browser specific problems

#### \,

• \, inserts the smallest predefined space in a formula
• Equivalent: \hspace{2}
• Ex.: $$a\,b$$ gives $a\,b$
• Ex.: $$a~\hspace{2}~b$$ gives also $a~\hspace{2}~b$

#### \;

• \; (backslash semicolon) inserts the third smallest predefined space in a formula
• Equivalent: \hspace{6}
• Ex.: $$a\;b$$ gives $a\;b$
• Ex.: $$a~\hspace{6}~b$$ gives also $a~\hspace{6}~b$

#### \:

• \: inserts the second smallest predefined space in a formula
• Equivalent: \hspace{4}
• Ex.: $$a\:b$$ gives $a\:b$
• Ex.: $$a~\hspace{4}~b$$ gives also $a~\hspace{4}~b$

#### \/ (backslash slash)

• \/ (backslash slash) avoids ligatures
• Ex.: $$V\/A$$ gives $V\/A$ in contrast to $$VA$$ which gives $VA$

#### \~

• In order to prevent some browser specific problems with whitespaces, it is advisable to use ~ (tilde) as the whitespace instead of the normal blank key (in places where whitespaces are mandatory, e.g. after commands).
• Ex.: $$\frac~xy$$ to produce $\frac~xy$
• Ex.: $$\sqrt~n$$ to produce $\sqrt~n$

#### \hspace{n}

• inserts a space of n pixels
• Ex.: $$f(x)\hspace{6}=\hspace{6}0$$ gives $f(x)\hspace{6}=\hspace{6}0$
• can be combined with the preceding command \unitlength{m}(default: m=1px) , which defines the applied unit
• Ex.: $$\unitlength{20}a\hspace{2}b$$ gives $\unitlength{20}a\hspace{2}b$ , i.e. a space of 20x2=40px

#### \LARGE (all capital letters)

• Everthing following the \LARGE command will be output in the largest predefined font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes!
• Ex.: $$\LARGE~3x$$ gives $\LARGE~3x$

#### \Large (L capital letter)

• Everthing following the \Large command will be output in the second largest font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes!
• Ex.: $$\Large~3x$$ gives $\Large~3x$

#### \large (all lower case letters)

• Everthing following the \large command will be output in the large font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes!
• Ex.: $$\large~3x$$ gives $\large~3x$
