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).
