Calculator:
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.

 

Trigonometric 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 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.
