testing the < math > tag

Some formulas are displayed with HTML. (The top line has extra spaces in the math tag to keep it from doing its thing and leave TeX is visible.)
< math > y = \alpha + \beta < /math > y = \alpha + \beta
Others will display with a png image. In either case, the software should do the right thing automatically.
< math >x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}< /math > x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

other ways

There are a few other ways to input other characters, too: HTML special symbols (e.g. "& alpha ;" without the spaces and utf-8 characters. How this shows up for you will depend on your browser and available fonts.
Here's the lowercase greek alphabet in utf-8 character.
(I used the Mac "Show Keyboard Palette" under "Keyboard" to type the characters.)

α β γ δ ε ζ η θ ι κλ μ ν ξο π ρ σ ς τ υ φ χ ψ ωϑ ϒ ϕ ϖ
Or using HTML symbols (e.g. "& alpha ;" without the spaces).
α β γ ...
or within individual math tags
\alpha \beta \gamma ...
or all in one tag
\alpha \beta \gamma

\frac{1}{\alpha + \gamma}

\frac{1}{1+\frac{1}{1+1}}
Is it true that \int_{-\infty}^{+\infty} e^{-x^2} dx = \sqrt{\pi} ?
