This course extends and integrates concepts from Algebra and Geometry. It is for students who are well-prepared for advanced mathematics and who will probably go on to take another mathematics course. Previous experience with trigonometry is helpful, but not a prerequisite. The pacing assumes that no review of second-year algebra is needed. Topics include a review of linear relations and functions, systems of linear equations, and the nature of graphs. Topics covered will include a study of polynomial, rational, exponential, logarithmic and trigonometric functions, inverse and second degree relations and their graphs. Other topics include complex numbers, polar coordinates, vectors, sequences and series.
