Joke of the day  You hear a news report on TV, and it says…At John F. Kennedy International Airport today, a Caucasian male (later discovered to be a high school mathematics teacher) was arrested trying to board a flight while in possession of a compass, a protractor and a graphical calculator.

According to law enforcement officials, he is believed to have ties to the Al-Gebra network. He will be charged with carrying weapons of math instruction.

Do trig functions have inverses? Only if we restrict the domains

Using inverses to find angles Cos -1 (-0.5) Sin x = 0.7 in 0 < x < 2∏

Practical application Enter data on p. 49 into L1 and L2 on your calculator. Calculate sinreg

homework P. 53 #24, 27- 30, 31,32,35 By Friday, p. 55 Quick Quiz 1-4. Must show work to get any credit.

Exit Slip True or false: The period of y = sin(x/2) is ∏. Justify your answer.
