Graphing ABCD sin graph

How do you manipulate a basic sin graph? Change the amplitude, period and phase shifts. You can change by typing in exact amounts, or grab the points and move them yourself. For fun, hit the play button and watch what happens.
What happens to the amplitude as it gets bigger or is negative? What happens to the graph as you make the b-value bigger? What about the period? Is there a relationship? Can you move the graph left or right, up or down? How?
