Course Outline

 

Course Description:

Precalculus is a prerequisite for calculus and for most courses in science and engineering. It provides an essential background for many other college-level mathematics courses. The topics covered in this course include the real number system; algebraic, exponential, logarithmic, trigonometric, and inverse functions; polynomials; and systems of equations. Graphing calculators are utilized to further illustrate many concepts.
