Required: Students must buy an access code to MyMathLab, an online course management system which includes a complete eBook; students will first need a Course ID provided by the instructor in order to register; online purchase of MyMathLab access at www.mymathlab.com; hard copies of access codes available with ISBN: 9780321199911
Hardbound text (optional): 9780321671776
Hardbound text + free MyMathLab access: 9780321828101
Graphing Calculator required. TI 83, TI 84 or TI 86 series calculators recommended.
Calculators capable of symbolic manipulation will not be allowed on tests. Examples include, but are not limited to, TI 89, TI 92, and Nspire CAS models and HP 48 models.
Neither cell phones nor PDA’s can be used as calculators. Calculators may be cleared before tests.
There is a collection of facts, formulas and identities from this course that students should be expected to memorize because having them at ready recollection is essential for their success in Precalculus, Calculus and beyond. Instructors should design test items that require these formulas in order to assess whether they have been learned. Students must not be allowed to bring these to the test on a formula sheet nor should instructors provide these formulas to them.
