Developed by a retired mathematics professor from Coventry University, this website "is a collection of separate units, in chronological topic-order, intended to service foundation level and first year degree level courses in higher education, especially those delivered in a modular style." Although there are separate sections for students and teachers, both contain essentially the same...

Developed by Dr. Abdelkader Dendane, a lecturer at the United Arab Emirates University, the Analyze Math website is designed to provide curious minds with access to in-depth tutorials on such topics as logarithmic functions, systems of linear equations, and calculus. The site also covers materials from the fields of trigonometry and the sometimes vexing field of statistics. Utilizing Java applets,...

This resource, provided by Professor David Joyce of Clark University, is an excellent examples of how Java can be used to explain basic principles of geometry and trigonometry. A Short Course in Trigonometry is divided into thirteen sections, accompanied by instructive Java applets and selected answered exercises. Professor Joyce shows a wonderful ability to simplify complex concepts and demystify...

The Khan Academy is a "not-for-profit with the goal of changing education for the better by providing a free world-class education to anyone anywhere. " Designed as a type of educational tool and a living archive, the site contains over 2100 videos that include algebra lessons, calculus sessions, cosmology, and developmental math. The "tool" function comes in when visitors discover that they can...

The Khan Academy's variegated lessons can serve as a supplement to more traditional, face-to-face math instruction, providing students with helpful resources to tackle everything from basic to complex math. This comprehensive treatment of right triangles and trigonometry offers a balanced overview of a range of topics, starting with the Pythagorean Theorem and progressing through special right...

Humans have long been interested in looking up into the sky and trying to figure out the nature of the planets, the sun, and the moon. Many ancient civilizations were able to systematically observe the sky and eventually they worked out mathematical schemes to describe what they found there. In this compelling article by Sandra M. Caravella, she takes a close look into how they were able to make...

High school or college students taking an introductory trigonometry course may find this site useful. Three modules comprise the site, and each provides an overview of basic concepts. Some of the most common trigonometric identities are explained and illustrated in example problems. Each module is accompanied by an interactive set of problems that test the user's understanding of the concepts....
