Latex formula usages:

• $latex_formula$ or \(latex_formula\), for inline equations, like $a+b$ or \(a+b\) in latex
• $$latex_formula$$ or \[latex_formula\], for displayed equations, like $$a+b$$ or \[a+b\] in latex
• \%label, latex_formula\%, for labeled displayed equations,
• EQ(label) can be used anywhere on the page as an anchor to the equation

For example, \(A_B+C\) produces $A_B+C$, \[A_B\] produces $$A_B,$$ and \%eq1, A_B.\% produces \%eq1, A_B.\% Now EQ(eq1) can be used to refer to EQ(eq1).
