New Idea - Slide Panel with Common Equations

A nice addition to the equation editor would be a scrolling panel that contains commonly used equations. These could exist under a variety of heading.

Example might include:

Algebra

$\sqrt{a^+b^2}$

$\sqrt{b^2-4ac}$

$\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Derivatives

$\frac{dy}{dx}$

$\frac{\Delta y}{\Delta x}$

$\frac{\delta y}{\delta x}$

$\frac{\partial y}{\partial x}$

Statistics

$\frac{n!}{r!(n-r)!}$

$\sum_{i=1}^{n}{X_i}$

$\sum_{i=1}^{n}{X_i^2}$

$\sum_{i=1}^{n}{X_i Y_i}$

$\sum_{i=1}^{n}{X_i Y_i}$

$\sum_{i=1}^{n}{(X_i - \overline{X})^2}$

$X_1, \cdots,X_n$

$\frac{x-\mu}{\sigma}$

Matrices

$\begin{pmatrix} a_{11} & a_{12} \\ a_{21} & a_{22} \end{pmatrix}$

$\begin{pmatrix} a_{11} & a_{12} & a_{13}\\ a_{21} & a_{22} & a_{23}\\ a_{31} & a_{32} & a_{33} \end{pmatrix}$

$\begin{pmatrix} a_{11} & \cdots & a_{1n}\\ \vdots & \ddots & \vdots\\ a_{m1} & \cdots & a_{mn} \end{pmatrix}$

$\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}$

Sets

$\bigcup_{i=1}^{n}{X_i}$

$\bigcap_{i=1}^{n}{X_i}$

Trig

$\cos^{-1}\theta$

$\sin^{-1}\theta$

$e^{i \theta}$

$\left(\frac{\pi}{2}-\theta \right )$

Geometry

$\overrightarrow{AB}$

$\overleftrightarrow{AB}$

$\widehat{AB}$

$\Delta A B C$

$\angle$

$\measuredangle$

$\sphericalangle$

Chemistry

$_{10}^{5}C^{16}$

$2H_2 + O_2 \xrightarrow{n,m}2H_2O$

$A\underset{b}{\overset{a}{\longleftrightarrow}}B$

$A\underset{0}{\overset{a}{\rightleftarrows}}B$

$A\underset{0^{\circ}C }{\overset{100^{\circ}C}{\rightleftarrows}}B$
