Thinking About Identities
Here is a great little ThinkQuest on how to solve trig identities. They have some excellent worked examples of quite challenging identites followed by some identities for you to prove. If you've been finding this unit difficult the students that built this site also did an excellent job of explaining what to look for in solving identities and how to go about it.
After looking at the trig identities ThinkQuest you might be interested in making one of your own. It's challenging and takes a lot ot time and energy. But, if you're interested talk to me about it. You might be interested in looking through the ThinkQuest Library for more inspiration or lots of good educational websites made by students for students.
