Equation Syntax

How-to use JsMath and the proper equation sytax:

Thanks for showing interest in taking your math2 knowledge to the next level.. The following will provide a brief overview of how to insert an equation into math2. Also examples will be provided so you can learn the tricks of the trade.

How to insert an equation into math^2:

Two different types of equation can be inserted into math2, one is inserted within text and looks like this: [++{$...$}++] . And one will be centered and padded. That one is done like this:

[++{$$...$$}++]

A few notes: The only difference between the two are the additional dollar signs (\$) that show up. Also the addition symbols (+) are meant to increase the size of the equation. I normally use 1 addition symbol for equations that will be centered and 2 if it will be inside of some text (this is what i have found to look the best).

Examples of equations being used:

To see how any equation is written, you can double click on the equation and an editor will appear. I have provided a few examples below and also links to many more examples for your use.

There are also multiple online equation editors for the LaTex format (see 1, 2, 3)

A_s = {M_u\over {øf_y(d-λ})}
A = {{20000\times \theta_s}\over l^{\raise1pt 2}_s}
ST = {Y_c\over {\sin \theta_s}}
1+\left(1\over 1-x^2\right)^3
p_1(n) = \lim_{m\to\infty} \sum_{\nu=0}^\infty \bigl(1-\cos^{2m}(\nu!^n\pi/n)\bigr)
ρ_t = 0.0018\left(60,000\over f_y\right) > 0.0014
Matrix:

\begin{bmatrix}2 & 3 & 5\\ 4 & 3 & z \end{bmatrix}

Equation Array:

\begin{eqnarray} && \int 1 = x + C \\ && \int x = \frac{x^2}{2} + C \\ && \int x^2 = \frac{x^3}{3} + C \end{eqnarray}
