[b]Students:[/b][br][br]In the applet below, note the graph of the trigonometric function displayed. [br][color=#9900ff]Then, write a correct trigonometric function (in the input box provided) whose graph is the graph shown. [br][br]Once you enter a function, the graph of the function you input will appear purple. [/color] [br]Keep modifying your function until the purple graph lies perfectly on top of the black graph. [br][br]You can zoom in or out if need be.
