Project: Geometric Proofs

As discussed in class, many of our trig identities cannot be proved using algebraic techniques. We must rely on Geometric Proofs to fill in this void.

Be sure you obey the following conventions:

1. If there are unobvious measures of lengths or angles stated on your diagram, you must explain where these measures come from. For example, if a side of a figure is labeled "b cos x", you must explain where this length comes from using the diagram.
2. Your narrative should be logical and move in a step-by-step manner from start to finish. Be sure to have someone read it BEFORE you turn it in.
3. If additional questions appear on your diagram, you must also address/answer these in the body of your paper for full credit on the project.

You must word-process the body of the document. However, you can hand print mathematical symbols/equations if you cannot find them in your word processor. (In Word, you can pull down "Insert" menu and click on "Symbol" to get most math symbols you need.) Please include one or more copies of your diagram in your paper so I can tell which proof you are working on. You may want to use color on your diagrams to better illustrate your proof.

This project is due at the beginning of class Wednesday, November 12. Bring the project to class; do NOT put it in the Homework Box.

Get started early – seeing things geometrically is not easy. Have fun!
