    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?

  2. 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.

  3. 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!
