Trigonometry - from MathWorld
From Cutting Edge
Eric Weisstein and Wolfram Research have built up a staggering number of math reference pages, all of which have extensive notation, diagrams, and examples. The trigonometry section covers basic trigonometry, identities, and angles, and also has material on more advanced topics such as spherical trigonometry, directed angles, and surveying. As with all the MathWorld sites, the information is abstracted and presented with the very advanced student in mind.
