Here are some formulas:

- α
- x n+y n≠z n

Some inline maths: ∑ n=1 ∞(−1 ) n n=ln 2 .

Some display maths:

∑ n=1 ∞1 n
`\sum_{n=1}^\infty \frac{1}{n}`
(1)∑ n=1 ∞1 n is divergent, but lim n→∞∑ i=1 n 1 i−ln n exists.
`\sum_{n=1}^\infty \frac{1}{n} \text{ is divergent, but } \lim_{n \to \infty} \sum_{i=1}^n \frac{1}{i} - \ln n \text{ exists.}`

Some random AMSTeX symbols - thanks to Robin Snader for adding these:

Note that ĝ , J, and γ 1 γ 2 all restrict to

x 1 x 2 ‾⊕x 2 x 1 ‾ and that this module is linear in x 1 and x 2 .

See label (1).

`\href{#hello}{\alpha+\beta}`

## Cross references

The following are 4 equations, labeled A,B,C,D:

(2)α
`\alpha`
(3)β
`\beta`
(4)γ
`\gamma`
(5)δ
`\delta`

You can now refer to (2), (3), (4), (5).
