This glossary is intended to provide a basic explanation of how a number of common mathematical terms are used. Definitions can be very slippery and confusing and at worst can replace one difficult term with a large number of other puzzling concepts. Therefore, where an easy definition is available it is provided here, where this has not been possible an example is used. If you require more detailed or complete definitions, you should refer to one of the very good mathematical dictionaries th

The making of the UK was complex and fraught with violent confrontations, particularly virule

To improve aerobic fitness the ACSM recommends exercise that employs large muscle groups, is rhythmic or dynamic, can be maintained continuously and is aerobic in nature (Garber et al., 2011). This type of exercise results in larger increases in aerobic fitness. Activities that would fit into this category include walking, running, swimming and cycling. This again depends upon the level of the individual and their goals and demands of their activity or sport.
