## Section heading - some pseudo-maths

A link to a section below.

Some reminder

Know that $e i π + 1 = ∑ n = 0 ∞ i π n n ! + 1 = 0 ,$ and stand in awe.

Equations can be inline. A question: is $\varnothing \in {\varnothing }^{c}$?

You can also have numbered equations. We have

 $Card ℤ = ℵ 0 < Card 2 ℤ = Card ℝ = c < Card ℝ ℝ$
which is nice.

## Unbulleted list

These are used for proofs.

1. The first list item.
2. Another list item.
3. A list item with a forced label.
4. Another list item with a forced label > 26.

## A braceted numbered list

These are used in problem sheets. Now with automatic numbering. Some questions are as follows.

 What does it mean for a function $f\left(x\right)$ to be continuous at $x=a$? Explain how to test if a function is continuous at $x=a$. What does it mean for a function $f\left(x\right)$ to be differentiable at $x=a$? Explain how to test if a function is differentiable at $x=a$. What does ${\left(df/dx\right)|}_{x=a}$ indicate about the graph of $y=f\left(x\right)$? Explain why this is true.

## Embedded SVG images

A diagram which uses param.js.

Some sort of 4-way diagram.

Some sort of 3-way diagram.

 Proof. (b) $⇒$ (a): Let $ℱ$ be a filter and let $\stackrel{‾}{ℱ}$ Something else.

Some text.

A proposition.

A lemma.

A theorem.

A corollary.
