Explorer Aplets

Explorer Aplets are designed to facilitate explorations of function families. These Aplets include the Quadratic Explorer and Trig Explorer. Each of these
Aplets has multiple views, however, in both cases, the Symbolic and Plot views appear identical. The only difference between these two views is in the con-
trol of the environment. While in the Plot view, you manipulate the graph and see the effect on the equation; in the Symbolic view, you change the values
of the equation parameters and see the effect on the graph. Both Aplets are unique in that the Plot view is the default view for the Aplet.

The Quadratic Explorer Aplet

The Quadratic Explorer Aplet is a micro-environment for exploring the relationships among the various representations of quadratic functions. Press APLET,
scroll to the Quadratic Explorer Aplet, and press the START menu key to get started. Table 1- 1 2 summarizes the functionality of the Aplet. The Quadratic
