You can now use MathJax (LaTeX)!

I know you all love to format your math equations beautifully. Well now you can!

use

Code:

\(....\)

for inline text

use

Code:

\[....\]

for centered display style text.

Examples:

Code:

\[x=\dfrac{2^2-\frac{1}{2}}{e^7}\]

\[x=\dfrac{2^2-\frac{1}{2}}{e^7}\]

Code:

Using the difference of two squares we obtain: \(a^2-4=(a+2)(a-2)\)

Using the difference of two squares we obtain: \(a^2-4=(a+2)(a-2)\)

Integrals and roots:

Code:

\[F'(x)=\dfrac{d}{dx}\int_a^x\sqrt{\sin^2(2t)+1} \ dt= 2\sqrt{\sin^2(2x)+1}\]

\[F'(x)=\dfrac{d}{dx}\int_a^x\sqrt{\sin^2(2t)+1} \ dt\]

Probability/Summations/Counting

Code:

\[P(x)=\sum_{k=0}^n {n\choose k} p^x(1-p)^{n-x}\]

\[\sum_{k=0}^n {n\choose k} p^x(1-p)^{n-k}\]


For more complicated things,

Code:

inline: $...$        and  centered/display style: $$......$$

tables/matices

Code:

$$\left(\begin{array}{cc}
\epsilon & \delta \\
\psi & \Phi \\
\end{array}\right)

\left[\begin{array}{c}
\sigma \\
\alpha \\
\end{array}\right]$$


$$\left(\begin{array}{cc}
\epsilon & \delta \\
\psi & \Phi \\
\end{array}\right)

\left[\begin{array}{c}
\sigma \\
\alpha \\
\end{array}\right]$$
