Worksheet3 Applets

Notation for these Applets

All of these Java applets work with "expressions" such as "x+3" or "sqrt(k*t)". Expressions can use the operators +, -, *, /, ^, and ** (where both ^ and ** indicate exponentiation), and they can use the mathematical constants pi and e. They can use various mathematical functions: sin, cos, tan, sec, cot, csc, arcsin, arccos, arctan, exp, ln, log2, log10, abs, sqrt, trunc, round, floor, ceiling, and cubert. (Here, "abs" is the absolute value function and "cubert" is the cube root function.)  

Java Components for Mathematics (JCM) Project

THE "Java Components For Mathematics" project, under the direction of David Eck at Hobart and William Smith Colleges, represents an effort to develop a framework of configurable mathematical software components written in the Java programming language. These Java components are meant to be used on instructional Web pages as interactive illustrations, special-purpose calculators, support for exercises, and so forth. The components in Version 1 (August 2001) are mostly useful for calculus and pre-calculus and for science courses that use some of the same material. They use Java 1.1, and so will not work in some older browsers that support only Java 1.0.

The applets on this page were quite easily (quickly, painlessly, usefully) created by John Pais, using and adapting David Eck's thoughtfully designed JCM applets, well-chosen examples, and terrific documentation.
