Could you paste the text from the power point into a Word Document for those of us without powerpoint on our computers at home? Or is there a way to open it without actually having powerpoint on our computer?

Well, not sure about doing it as a word file, since much of the ppts have equations in them and stuff. BUT, you can download a free viewer at this address:

I hope this helps.

Here are the strategies.

Only one side at a time
More complicated side first
Look for chances to use the fundamental identities
Combine fractions over a common denominator
Look for chances to factor
Look for difference of two squares chances
Look for buddies: sin-cos, sec-tan, csc-cot
If stuck, convert to sines and cosines
Always try SOMETHING!
