# Calculators and Technology

These posts are about graphing calculators and technology. They show ways to use graphing calculators to explore calculus concepts.  Graphing calculators and other technology, such as those available on smart phones and iPads, can and should be used all through the year to help students see and understand the concepts.

The AP Exams require the use of a graphing calculator.

Students will not be able to answer some the question without using their graphing calculator. Calculators must be from the approved list – graphing, not scientific, no Qwerty keyboards, no wireless communication ability. The first two post discuss the basics.
