Students in Pre-calculus will extend their understanding and ability in mathematics through studying the underpinnings of calculus. Functions will be used to model real-world phenomena. Trigonometry, including periodic and circular functions, as well as the properties and identities of trigonometry constitute a major portion of the course. Elementary functions, fitting functions to data, probability and functions of a random variable will be studied. Modeling will continue with the mathematics of vectors, matrices, conic sections, polar coordinates, and complex numbers. The course will end with a study of sequences and series and the introduction of limits.
