Select each function one at a time.
Change the value of the B slider.
State the domain and range of each.
State the length of the period for each.
State the amplitude of each.
Can you state the domain and period for the inverse of each function?

Which function have a base period of 0 throught 2π? Which function has a base period of π? For which functions is it convenient to start the domain at -π/2? What is the domain of each of these?
