Pre-Calculus students expand their graphing techniques and algebra skills in preparation for calculus. Students begin coursework with a review of quadratic functions and tackle questions involving practical applications, including projectile motion. After mastering algebraic techniques including completing the square and factoring completely, students expand on this by studying the algebraic and graphic characteristics of polynomial and rational functions. In this course, students also have the opportunity to develop a deeper understanding of exponential and logarithmic relationships by studying real-world scenarios involving compound interest and radioactive decay. Much of the second semester of this course focuses on expanding students’ knowledge of trigonometry, as students study the uses of trigonometric functions through both the right triangle and unit circle approach. Studies in trigonometry include advanced algebraic concepts (including solving trigonometric equations involving the substitution of identities) and graphic analysis (including graphing equations of trigonometric functions with different amplitudes and frequencies). Thorough knowledge of the material in this course is essential for success in calculus. Prerequisite: Successful completion of Algebra 2/Trigonometry and Geometry
