Roots of a sinusoidal + graphing

Last class was putting everything together we have been studying for the past few classes. Homework (which is due Friday); for each of the following four functions:

• Find the transformations of the graph y=sinx or y=cosx
• State the mapping rule
• List a TOV for one period
• Graph the function
• Find the roots
• State the equation of the sinusoidal axis, the amplitude, and the period

(1/2)(y+1) = sin(x+90)

-(1/2)(y-2) = cos(3x)

-4(y+4) = sin[5(x+30)]

-(y-1) = cos[1/2(x+3)]

Todays class will be in-class work on the independent project. Next checkpoint date is THURSDAY, NOVEMBER 16TH.
