Precalculus covers a number of areas such as;

• functions;
• periodic functions and applications;
• trigonometric identities and parametric equations;
• triangle trigonometry;
• probability and data;
• matrices and vectors;
• sequences and series;
• complex numbers; and
• an introduction to the derivative and rates of change.

M•S•R will be adding a number of MathCasts which will cover some of these areas.
