Electrochemistry: interconversion of electrical energy and
chemical energy. Electrical effects occur as a result of the
movement of electrical charge, either as ions in solution
or electrons in a conductor.

Surds, and other roots
mc-TY-surds-2009-1
Roots and powers are closely related, but only some roots can be written as whole numbers.
Surds are roots which cannot be written in this way. Nevertheless, it is possible to manipulate
surds, and to simplify for
Polynomial functions
mc-TY-polynomial-2009-1
Many common functions are polynomial functions. In this unit we describe polynomial functions
and look at some of their properties.
In order to master the techniques explained here it is vital that you undertak
Polynomial division
mc-TY-polydiv-2009-1
In order to simplify certain sorts of algebraic fraction we need a process known as polynomial
division. This unit describes this process.
In order to master the techniques explained here it is vital that you under
Indices or Powers
mc-TY-indicespowers-2009-1
A knowledge of powers, or indices as they are often called, is essential for an understanding
of most algebraic processes. In this section of text you will learn about powers and rules for
manipulating them thr
Factorising quadratics
mc-TY-factorisingquadratics-2009-1
An essential skill in many applications is the ability to factorise quadratic expressions. In this unit
you will see that this can be thought of as reversing the process used to remove or multiply-
