Typesetting Mathematics

I specifically chose WordPress for this blog because of it allows the use of \LaTeX for typesetting mathematics, used by many mathematicians and scientists for writing documents with extensive mathematical symbols.

To use \LaTeX in WordPress, the basic command is

\$\hbox{latex [Your LaTeX command here]} \$

This creates a small image rendering the mathematical symbols. If you hover your mouse over any \LaTeX image, you should see the source code that made the image possible.

If you’re not familiar with \LaTeX, I’ve illustrated some common syntax with the examples below.  The text on the left should replace [Your LaTex command here] above.

  1. y = a(x-h)^2 + k   becomes  y = a(x-h)^2 + k
  2. \frac{x^2-y^2}{x-y} = x + y \hbox{~if~} x \ne  y  becomes \frac{x^2-y^2}{x-y} = x + y \hbox{~if~} x \ne y
  3. \pi \approx \frac{22}{7}    becomes   \pi \approx \frac{22}{7}
  4. \pi \approx \displaystyle \frac{355}{113}   becomes  \pi \approx \displaystyle \frac{355}{113}
  5. a^2 + b^2 = c^2   becomes  a^2 + b^2 = c^2
  6. x \ge 6   becomes  x \ge 6
  7. \sqrt{x^2} = |x|  becomes  \sqrt{x^2} = |x|
  8. \sqrt[3]{-216} = -6  becomes \sqrt[3]{-216} = -6
  9. \log_{10} \frac{x}{y} = \log_{10} x – \log_{10} y   becomes \log_{10} \frac{x}{y} = \log_{10} x - \log_{10} y
  10. \sin^2 \theta + \cos^2 \theta = 1  becomes \sin^2 \theta + \cos^2 \theta = 1
  11. (x+y)^n = \displaystyle \sum_{k=0}^n {n \choose k} x^k y^{n-k}   becomes  (x+y)^n = \displaystyle \sum_{k=0}^n {n \choose k} x^k y^{n-k}
  12. \displaystyle \int_a^b f(x) dx \approx \frac{h}{2} \left[ f(x_0) + 2f(x_1) + \dots + 2f(x_{n-1}) + f(x_n) \right]   becomes \displaystyle \int_a^b f(x) dx \approx \frac{h}{2} \left[ f(x_0) + 2f(x_1) + \dots + 2f(x_{n-1}) + f(x_n) \right]
  13. \frac{d}{d\phi} \left(\tan^2 \phi\right) = 2 \tan \phi\sec^2 \phibecomes \frac{d}{d\phi} \left( \tan^2 \phi\right) = 2 \tan \phi\sec^2 \phi
  14. \mathbb{Z} \subset \mathbb{Q} \subset \mathbb{R} \subset \mathbb{C}   becomes \mathbb{Z} \subset \mathbb{Q} \subset \mathbb{R} \subset \mathbb{C}
  15. \displaystyle \frac{-b \pm \sqrt{b^2-4ac}}{2a}   becomes \displaystyle \frac{-b \pm \sqrt{b^2-4ac}}{2a}
  16. P(A \cap B)   becomes P(A \cap B)
  17. \triangle ABC \cong \triangle DEF   becomes  \triangle ABC \cong \triangle DEF
  18. (-\infty,-2] \cup [2,\infty)  becomes (-\infty,2] \cup [2,\infty)
