Calculator:

Graphing Calculators may be required for some assignments/assessments at the discrection of the Instructor. 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.

Formulas:

**
**

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 future classes. 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.

**Textbook Sections**In some sections, not all objectives are covered. Required objectives are listed below. To clarify, examples that accompany objectives that can be skipped are listed. Instructors may cover additional objectives at their discretion. Although instructors may not necessarily assign all of the problems in the Suggested Exercise Blocks, in order to demonstrate proficiency in the learning outcomes of this course, students should be able to do any of the problems in these lists.
