Pre-calculus – mth225 (4 credits)

This course prepares students for success in calculus. A brief review of college algebra topics is presented including linear, polynomial, radical, rational and absolute value, functions, and equations. Students also examine systems of equations, exponential, logarithmic, and trigonometric functions as well as analytic geometry. In addition, students are introduced to sequences and series.

This undergraduate-level course is 7 weeks. This course is available to take individually or as part of a degree or certificate program. To enroll, speak with an Enrollment Representative.
