P

Psi (upper case greek letter)

$$\Psi$ gives \Psi$$

R

relativity

E=mc^2

rho (lower case greek letter)

$$\rho$ gives \rho$$

right only brace

  • Syntax: \left.{...\right}  (note the dot!)
  • Ex.: $$\left.{{\rm~term1\atop\rm~term2}\right}=y$ gives </li></ul><p align="center">\left.{{\rm~term1\atop\rm~term2}\right}=y$$

    (\rm~something switches to roman style)


root

  • Syntax: \sqrt[n]{arg} or simply  \sqrt{arg} for \sqrt[2]{arg}
  • Ex.: $$\sqrt[3]{8}$ gives</li></ul><p align="center">\sqrt[3]{8}$$

    • Ex.: $$\sqrt{-1}$ gives</li></ul><p align="center">\sqrt{-1}$$

      • Nesting of roots (and combining with fractions, ...etc.) are possible.
      • Ex.: $$\sqrt[n]{\frac{x^n-y^n}{1+u^{2n}}}$ gives</li></ul><p align="center">\sqrt[n]{\frac{x^n-y^n}{1+u^{2n}}}$$

        • Ex.: $$\sqrt[3]{-q+\sqrt{q^2+p^3}}$ gives</li></ul><p align="center">\sqrt[3]{-q+\sqrt{q^2+p^3}}$$


S

s.u.m

$$\sum_{n+2}^x$  is  \sum_{n+2}^x$$

sigma (lower case greek letter)

$$\sigma$ gives \sigma$$

Sigma (upper case greek letter)

$$\Sigma$ gives \Sigma$$

smiley

square bracket

  • Synatx: \left[...\right]
  • Ex.: $$\left[a,b\right]$ gives \left[a,b\right]$$
