Welcome!

The National Curve Bank is a resource for students of mathematics.  We strive to provide features - for example, animation and interaction - that a printed page cannot offer.  We also include geometrical, algebraic, and historical aspects of curves, the kinds of attributes that make the mathematics special and enrich classroom learning.

We welcome participation.  We encourage you to submit your best web animation as a "deposit" in the National Curve Bank.  Also, we welcome information about other outstanding sites that deal with the same subject.  We will provide links to your home site and thus give your work a wide audience.  Please see "Submit Your Curve" on the left for details.
