F

formula box

$$\fbox{x=\frac{1}{2}}$$  gives

$\fbox{x=\frac{1}{2}}$

fraction

• Syntax: \frac{numerator}{denominator}
• Use font sizing commands for specific sizing if you don't want the predefined one to be taken.
• Ex. (with predefined sizing): $$f(x,y)=\frac{2a}{x+y}$$ gives

$f(x,y)=\frac{2a}{x+y}$

• Ex. (with specific sizing): $$f(x,y)=\frac{\fs{2}2a}{\fs{2}x+y}$$ gives

$f(x,y)=\frac{\fs{2}2a}{\fs{2}x+y}$

• You may nest fractions as much as you want.
• Ex. (nested fractions): $$\frac{\frac{a}{x-y}+\frac{b}{x+y}}{1+\frac{a-b}{a+b}}$$ gives

$\frac{\frac{a}{x-y}+\frac{b}{x+y}}{1+\frac{a-b}{a+b}}$

G

gamma (lower case greek letter)

$$\gamma$$ gives $\gamma$

Gamma (upper case greek letter)

$$\Gamma$$ gives $\Gamma$

greater than

$$x>y$$  gives

$x>y$

greater than or equal

$$x\ge~y$$ or $$x\geq~y$$ gives

$x\ge~y$

greek letters (overview)

Simply write \greekletter for lower case and \Greekletter for upper case.

Here's a list of all known greek letters (Note: not all upper case greek letters are known):

Lower Case Greek Letters:

 Command Filter Expression Result \alpha $$\alpha$$ $\alpha$ \beta $$\beta$$ $\beta$ \gamma $$\gamma$$ $\gamma$ \delta $$\delta$$ $\delta$ \epsilon $$\epsilon$$ $\epsilon$ \varepsilon $$\varepsilon$$ $\varepsilon$ \zeta $$\zeta$$ $\zeta$ \eta $$\eta$$ $\eta$ \theta $$\theta$$ $\theta$ \vartheta $$\vartheta$$ $\vartheta$ \iota $$\iota$$ $\iota$ \kappa $$\kappa$$ $\kappa$ \lambda $$\lambda$$ $\lambda$ \mu $$\mu$$ $\mu$ \nu $$\nu$$ $\nu$ \xi $$\xi$$ $\xi$ o  (!) $$o$$ $o$ \pi $$\pi$$ $\pi$ \varpi $$\varpi$$ $\varpi$ \rho $$\rho$$ $\rho$ \varrho $$\varrho$$ $\varrho$ \sigma $$\sigma$$ $\sigma$ \varsigma $$\varsima$$ $\varsigma$ \tau $$\tau$$ $\tau$ \upsilon $$\upsilon$$ $\upsilon$ \phi $$\phi$$ $\phi$ \varphi $$\varphi$$ $\varphi$ \chi $$\chi$$ $\chi$ \psi $$\psi$$ $\psi$ \omega $$\omega$$ $\omega$

Upper Case Greek Letters:

 Command Filter Expression Result \Gamma $$\Gamma$$ $\Gamma$ \Delta $$\Delta$$ $\Delta$ \Theta $$\Theta$$ $\Theta$ \Lambda $$\Lambda$$ $\Lambda$ \Xi $$\Xi$$ $\Xi$ \Pi $$\Pi$$ $\Pi$ \Sigma $$\Sigma$$ $\Sigma$ \Upsilon $$\Upsilon$$ $\Upsilon$ \Phi $$\Phi$$ $\Phi$ \Psi $$\Psi$$ $\Psi$ \Omega $$\Omega$$ $\Omega$

I

infinity

$$\infty$$  gives $\infty$

integral

• General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

• In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
• Syntax for integral symbol:

$$\bigint_{0}^{\infty}$$   gives

$\bigint_{0}^{\infty}$

and

$$\int_{0}^{\infty}$$   gives

$\int_{0}^{\infty}$

• Use font size commands for a nicer picture:

$$\LARGE\bigint_{\small0}^{\small\infty}$$   gives

$\LARGE\bigint_{\small0}^{\small\infty}$

and

$$\large\int_{\small0}^{\small\infty}$$   gives

$\large\int_{\small0}^{\small\infty}$

iota (lower case greek letter)

$$\iota$$ gives $\iota$
