What You'll Learn
A full semester of precalculus — completed at your own pace, with no deadlines or fixed class times.
Learning Outcomes
What You'll Be Able to Do
✓Solve and graph linear, quadratic, polynomial, rational, exponential, logarithmic, and trigonometric equations and inequalities, including real-world applications
✓Analyze and interpret the behavior of functions — including domain, range, transformations, composition, and inverses — using algebraic and graphical methods
✓Model real-world scenarios with linear, polynomial, exponential, logarithmic, and trigonometric functions, selecting appropriate types and interpreting results
✓Apply degree and radian measure, the unit circle, and all six trigonometric functions to solve right triangles, oblique triangles (Law of Sines and Cosines), and applied problems
Course Curriculum
Your path through the course
Work through each lesson at your own pace and build your understanding step by step.
✓Evaluate and simplify trigonometric expressions using fundamental identities, sum/difference, double-angle, and half-angle formulas
✓Represent and interpret data in Cartesian, polar, and vector forms and connect representations across function types
✓Solve linear and nonlinear systems of equations using substitution, elimination, and matrix methods including Gaussian elimination
✓Compute the nth term and sum of arithmetic and geometric sequences and series, and apply the binomial theorem and basic probability concepts
