#### \_ (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$

#### \~

• 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.: $$\large~3x$gives$\large~3x$$
