Math 118 uses the accompanying WileyPLUS homework system which is integrated into Blackboard. Clicking any of the homework sets in Blackboard should prompt students to purchase the homework and textbook package. The USC bookstore also carries physical copies of the book with an activation code for WileyPLUS.
The following table lists the minimum set of topics to be included in this course. The number of lectures listed for each chapter is only a suggestion and will vary across instructors and semesters.
Math 118 specifically omits all trigonometry and trigonometric functions, notably Sections 1.10 and 3.5.
There are typically 42-43 lecture days in a semester, so lecture periods are available for exams.
