2/15  Trigonometric Identities
Homework: page 362 #21-33 odd, #40-56 all
    The sollowing identities were covered:

1. Reciprocals- cscX=(1/sinX)
                secX=(1/cosX)

2. Quotient Identity- tanX= (sinX/cosX)
                     cotX= (cosX/sinX)

3. Pythagoreom- cos^2X + sin^2X= 1
                1+tan^2X = sec^2X
                1+cot^2X = csc^2X
