# Functions and Graphs (Metric)

## Class Details

**Tom
Baker**

This class covers the idea of a function, composites and inverses, odd and even functions and specific functions including the modulus function, the exponential and logarithmic functions and the hyperbolic functions. Some of this is covered at A-level, and most of the rest is Further Maths.

## Units

### Functions in General

Composites, inverses, odd and even functions. This is an A-level topic, which Science and Engineering courses at Imperial will assume you know.

The inverse of a given function.

Odd and even functions; the odd and even parts of a function.

### Particular Functions

Modulus, Heaviside step, exponential and logarithmic functions. Apart from the Heaviside function, which is a university topic, this is covered at A-level and Science and Engineering courses will assume you know it.

### Hyperbolic Functions

The functions \(\sinh x\), \(\cosh x\) and \(\tanh x\), and their reciprocals and inverses. This is a Further Maths topic; Imperial courses that require Further Maths may assume you know it.
