Pre-Calculus Part 1
LI.MAT.301810.1.ML
Course Length: 1 Semester
Has Textbook: Yes
In Pre-Calculus Part 1, students develop a deeper understanding of functions and their graphs. The function types covered in depth in this course include polynomial, rational, exponential, logarithmic, and trigonometric. Topics covered in relation to polynomial and rational functions include complex numbers, zeroes of polynomial functions, and synthetic division. Some exponential and logarithmic topics discussed are change of base formulas, properties of logs, growth and decay, and logistic growth models. Pre-Calculus Part 1 concludes with the unit circle, trigonometric functions, and their inverses.
It is recommended that students possess a solid understanding of the concepts covered in Algebra II and Geometry or equivalent course work before enrolling in this course.
