Title: An Introduction to Limits
Address: http://www.wri.com/MathSource/Applications/Education/Secondary/0207-526/Limits(93).ma
Requires MathReader.
Description: This project is intended to be used near the beginning of a traditional course in introductory Calculus. Because the limit is in a sense the give that holds all of the calculus together, it is important that students have a clear understanding of this topic. This project is designed to provide the student with an intuitive feel for the limit by presenting a few common functions along with their graphs and tables of function values. Examples include functions whose limits do not exist for certain values of independent variable. Mathematica is used to calculate to what the limit should be in each example and animation is function values as the independent variable moves closer to a particular value from either direction.
