arclength issue?

[Jorge Garcia]

Hello everyone,

Why does the last line of this SAGE script crash?

ArcLength Question from AP Calculus BC class today!

We entered the same steps in a TI-84, a TI-89 and a TI-nSpire and got approximately 805.296 feet.

BTW, we were modeling a roller coaster ride and finding how far the roller coaster travels along one period where x is measured in feet..

TIA,

A. Jorge Garcia
