By looking at each variable and moving each of the sliders, find out what each of the constants a, b, c and d do when changed. Write down your observations in as detailed a way as possible.

Start with a=1, b=1, c=0 and d=0. [br]Change a, and describe what happens. Then put back to 1. [br]Change d, and describe what happens. Then return to 1. [br]Repeat for b and c. [br][br]Repeat this process for Cosine and Tangent functions.
