Today we learned more about chapter 5. We didn't learn any new identities unfortunately, but we did learn some rules to help make solving these problems a little easier.

The rules are....

1. Always work with one side of the equation and don't touch the other one.

2. Always look for ways to factor the expression first. If the expressions factor, its the first thing you should look for. Add fractions, square a binomial, or create a monomial denominator

3. Look for ways to use the identities. decide which functions are in the final expressions you want. Sines and cosines pair up nicely, as well as secants and cosecants and cotangents.

4. If the above rules haven't helped so far, try converting all terms to sines and cosines.

5. If all else fails, try something. Making an attempt is the first step in solving the problem!!

The homework was 5.1 numbers, 75, 78-80......5.2 numbers 19-22, 26-28, 40-43, 46, 51

Enjoy!!! :D
