Accuracy of Series Approximations
Accuracy of Series Approximations
In physics and mathematics, series expansions to approximate functions are often used because using the exact solution is either impossible or involves unnecessary complicated calculations. This Demonstration shows how accurate the series expansions for , , , , and are, and how adding terms increases that accuracy moving away from the origin.
