About Math Formula

• use tag: start <math>, and the end close it </math>. Like: $E=mc^{2}$

• $\alpha$

• Superscript $a^{x}$

• Subscript $b_{1}$

• Grouping $a^{x+y},i_{1...n}$

• Combining sub & super without and with horizontal separation $a_{2}^{3}$ or ${a_{2}}^{3}$

• Super super $a^{b^{x}}$

• Sum $\sum _{k=1}^{N}k^{2}$

• Sum (force \textstyle) $\textstyle \sum _{k=1}^{N}k^{2}$

• Product $\prod _{i=1}^{N}x_{i}$

• Product (force \textstyle) $\textstyle \prod _{i=1}^{N}x_{i}$

• Limit $\lim _{n\to \infty }x_{n}$

• Limit (force \textstyle) $\textstyle \lim _{n\to \infty }x_{n}$

• Fractions ${\frac {a}{b}}=c$ or use 'over' ${a \over b}=c$

• Small fractions ${\tfrac {x}{y}}=z$

• Matrices ${\begin{matrix}x&y\\z&v\end{matrix}}$

or ${\begin{vmatrix}x&y\\z&v\end{vmatrix}}$ or ${\begin{pmatrix}x&y\\z&v\end{pmatrix}}$ or ${\begin{bmatrix}x&y\\z&v\end{bmatrix}}$ or ${\begin{Bmatrix}x&y\\z&v\end{Bmatrix}}$ or ${\begin{bmatrix}0&\cdots &0\\\vdots &\ddots &\vdots \\0&\cdots &0\end{bmatrix}}$

• Parenthesizing big expressions, brackets, bars $\left({\frac {1}{2}}\right)$

• Simultaneous equations ${\begin{cases}3x+5y+z\\7x-2y+4z\\-6x+3y+2z\end{cases}}$

• Multiline equations ${\begin{aligned}f(x)&=(a+b)^{2}\\&=a^{2}+2ab+b^{2}\\\end{aligned}}$

• Multiline equations (more) ${\begin{array}{lcr}z&=&a\\f(x,y,z)&=&x+y+z\end{array}}$
