9.4.1 Maths Fonts

Just as we are able to change text fonts using the commands \textrm, \textbf etc, we can also use commands to change the maths font. Basic maths font changing commands are shown in Table 9.1.

**Table 9.1:** Maths Font Changing Commands
Command	Example Input	Corresponding Output
		(Computer Modern)
`\mathrm{<maths>}`	$\mathrm{xyz}$	$\cmmathrm{xyz}$
`\mathsf{<maths>}`	$\mathsf{xyz}$	$\cmmathsf{xyz}$
`\mathtt{<maths>}`	$\mathtt{xyz}$	$\cmmathtt{xyz}$
`\mathit{<maths>}`	$\mathit{xyz}$	$\cmmathit{xyz}$
`\mathbf{<maths>}`	$\mathbf{xyz}$	$\cmmathbf{xyz}$
`\mathcal{<maths>}`	$\mathcal{XYZ}$	$\cmmathcal{XYZ}$

The calligraphic fonts via \mathcal are only available for upper-case characters[Better script fonts for maths]. Table 9.2 lists additional font commands supplied with the amsmath and amsfonts packages.

**Table 9.2:** The `amsfonts`^‡ and `amsmath`^† Font Commands
Command	Example Input	Example Output
`^‡\mathbb{<maths>}`	$\mathbb{A+B=C}$	$\mathbb{A+B=C}$
`^‡\mathfrak{<maths>}`	$\mathfrak{A+B=C}$	$\mathfrak{A+B=C}$
`^†\boldsymbol{<maths>}`	$\boldsymbol{A+B=C}$	$\boldsymbol{A+B=C}$
`^†\pmb{<symbol>}`	$\pmb{+-=}$	$\pmb{+-=}$
