## SAO Mathematical Requirements

Astronomy is based on mathematics. Our introductory units focus on a conceptual approach to astronomy but will at times require some basic mathematics. Advanced SAO units, however, do require some background mathematical experience.
**Mathematics Background**

The **introductory-level units**, *AST80005 Exploring the Solar System,*
*AST80004 Exploring Stars & the Milky Way*, *AST80006 Galaxies and their
Place in the Universe* and *AST80008 History of Astronomy*,
may require some basic maths (i.e via our newsgroup discussions, and as part of Computer Managed Tests).
The more **advanced-level units** *AST80003 Cosmology and the Large-scale Structure of the Universe,
AST80016 Stellar Astrophysics* and *AST80011 Major Project: Computational Astrophysics*, assume some
background mathematical knowledge. The following summary is a
good guide for advanced-level units currently being offered:

__Basic Algebra:__

rules of algebra, functions, equations, cartesian coordinates, linear equations, graphs of simple equations, exponential functions & logarithms__Basic Geometry & Trigonometry:__

straight lines, circles, ellipses, parabolas, spheres, definition & manipulation of simple trigonometric functions such as sine, cosine & tangent__Calculus:__

graphical interpretation of differentiation & integration, eg. rate of change, instantaneous slope of a curve & differentiation, area under a curve & integration (integration & differentiation of mathematical expressions not required)

If other maths concepts & techniques are required, we will teach them as part of our course material.

Note that **all** SAO course material contain some mathematical equations - this is astronomy after all! Similarly, some questions in
the computer managed tests that form part of the assessment may contain simple maths questions. These will usually be algebra of the
type presented in the course material.

**Bridging Mathematics**

Course participants wishing to "brush up" their mathematics can use the above mathematics topics as a guide, and study from any suitable text.

As an alternative, for self-paced revision we can recommend:

**MathCasts**: MathsCasts are produced by the mathematics support centres at Swinburne University, the University of Limerick and Loughborough University. They are part of an ongoing collaborative research project to develop high quality resources and investigate the effectiveness of MathsCasts to support mathematics learning. They are targeted at prerequisite to first year level, in a range of subjects such as: Engineering, Sciences, Business, Computing and Technology.
