**Setting Bounds**

Calculus gives access to quick approximations through various methods. But how accurate are these approximations? Students frequently struggle in dealing with errors of approximation. This session will explore using TI-Nspire™ CX technology in various ways to help students visualize both error bounds and the methods used to find them. As “Alternating Series Error Bound” is added to the AP* exam this year, we will address this topic and its difference from “Lagrange Error Bound” using the Mathematical Practices for AP* Calculus (MPACs).
