Pre-Calculus Essentials for Computer Science

Welcome to preparations for Calculus I. This prerequisite information offered by the Math Center is for students entering the BS Computer Science program. It is designed to refresh and emphasize mathematical mechanics that prepare you for engagement in Calculus I in the first term of your program. We will use a customized e-text by OpenStax that incorporates instruction, guided practice, and module exercises.  


Note: Students who elect to engage this material will not receive credit for work completed toward a degree or other formal award. Since this activity is not credit-bearing, there are no associated course costs and it is not eligible for financial aid funding. There is no assessment associated with this material and no indication of a pass or not pass will be granted for engagement.
