Trigonometry gives a thorough study of circular functions followed by applications to triangular situations. Instruction includes the study of theory through trigonometric equations and identities, and an introduction to vectors. Pre-Calculus provides students with an introduction to a number of topics central to the study of calculus, while completing the study of polynomial, logarithmic, exponential, rational functions began earlier in coursework. In addition, Pre-Calculus gives students a strong introduction to analytic geometry, complex numbers, limits, and sequences and series. The math faculty recommends the TI 84 family of calculators.
