Math Notation Help

• The command character "^" triggers superscription of the following expression(s).
• For more than one superscripted character put them in braces {...}.
• Use font sizing commands for appropriate sizing.
• Ex.: $$x^2$$ gives

$x^2$

• Ex.: $$a^{m+2n}$$ gives

$a^{m+2n}$

• Ex. (with specific sizing): $$x^{\small2}=a^{\small{m+2n}}$$ gives

$x^{\small2}=a^{\small{m+2n}}$

• Combine superscripting with subscripting (command character "_").
  Syntax: Expr_{subExpr}^{supExpr}.
• Ex.: $$A_{\small{i,j,k}}^{\small{-n+2}}$$ gives

$A_{\small{i,j,k}}^{\small{-n+2}}$

• Variables in formulas are rendered in italic roman font face, which is a widely used convention.
• Following this convention, constants are shown as non-italic.
• Exp.: $$f(x)=3a+x$$ gives

$f(x)=3a+x$

• Everthing following the \LARGE command will be output in the largest predefined font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes! 
• Ex.: $$\LARGE~3x$$ gives $\LARGE~3x$

• Everthing following the \Large command will be output in the second largest font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes! 
• Ex.: $$\Large~3x$$ gives $\Large~3x$

• Everthing following the \large command will be output in the large font size until the system encounters another font size command.
• Note: This command is case sensitive, since large, Large and LARGE are different sizes! 
• Ex.: $$\large~3x$$ gives $\large~3x$

• Everthing following the \normalsize command will be output in the smallest predefined font size until the system encounters another font size command.
• \normalsize is the default font size, i.e. the size automatically chosen if there is no font size command
• Ex.: $$\normalsize~3x$$ gives $\normalsize~3x$

• \small
• Ex.: $$\small~3x$$ gives $\small~3x$

• Everthing following the \tiny command will be output in the smallest predefined font size until the system encounters another font size command.
• Ex.: $$\tiny~3x$$ gives $\tiny~3x$

• Syntax: \left<...\right>
• Ex.: $$\left<f,g\right>$$ gives

$\left$
