Can anyone be a maths genius? – includes Marcus du Sautoy’s top tips.

Not sure that I get what this is all about, but interesting to discover it on the back of finding out about the simple english wikipedia. Where does the artistic element come into it?

at the Simple English Wikipedia — ratio.

Optimisation: some notes and commentary on how to approach these problems, at least as I see them.

Heinemann Higher Mathematics Ex 6Q Question 4:

Key points:

one-to-one correspondence

This topic will introduce some concepts which are useful for later parts of the course, so again please make a good effort to understand its content. While it could be thought of as a “helper” topic questions on this topic, in its own right, may also occur in the exam.

By the end of this topic you should understand

- what a set is
- what a function or mapping is
- what the domain of a function is
- what the range of a function is
- what a composite function is
- that f(g(x)) != g(f(x)) in general [!= means “not equal to”]
- one-to-one correspondence
- about the inverse function
- the effect of applying a function and then its inverse
- the graph of the inverse function is found by reflecting the graph of the function in the line y = x
- about exponential functions to a given base a
- about logarithmic functions to a given base a

The content of this topic is more abstract than the rest of the course but it will make topics to be encountered later on that are difficult, much easier to understand, and so this topic should not be dismissed as unimportant, or as a standalone topic.
