## Calculators

All students should have access to a scientific calculator. The make and model are not important, but at a minimum the calculator should include trigonometric, exponential and logarithmic functions, a square root key, scientific notation, and the irrational numbers π, e

**This year, the Mathematics Department is transitioning from TI-84 technology to the more powerful, TI-Nspire technology as the primary instructional tool in the classroom. During the transition, teachers will be using both technologies. Students who are considering buying a graphing calculator should purchase a TI-Nspire CX CAS. A limited number are available for purchase at the Gunn Math Department. For more information see our home page.**

A graphing calcultor is required for the Advanced Placement Examinations in Calculus and Statistics. College Board has a clearly stated calculator policy for both Statistics and Calculus. Graphing calculators are used regularly in courses that lead up to calculus to help students learn how to use the calculators effectively.

A graphing calculator is required in the following courses: Algebra2/Trigonometry A, Introduction to Analysis and Calculus, Trigonometry/Analytic Geometry Honnors, Analysis Honors, AB Calculus AP, Statistics AP

A graphing calculator is recommended in : Algebra 1A, Algebra 2, Precalculus.

There are certain units where students are not permitted to use a graphing calculator on the unit test. For example, in an Algebra unit on graphing a linear equation, students will be required to graph a line without the use of technology and the use of a graphing calculator might be prohibited. Alternately, sometimes students are permitted to use a TI-84 Plus but not a TI-89 because of the advanced functions of the TI-89 calculator.

Over the next 2 years, Gunn math teachers will be transitioning from the TI-84 Plus to the TI-Nspire CAS. Please note that the TI-Nspire CAS can only be purchased online. It is possible to purchase a TI Nspire CX at many retail outlets, however the TI-Nspire CX does not have the full funtionality of a "Calculator Algebra System" (CAS).
