- Mess around with the applet.
- Consider the white curve, y = a sin (bx + c) + d. Explain what
changing each of the
parameters does to the curve, making sure to carefully distinguish between
the effects of a and b.
- If you followed step (1), you would have wound up with a red curve on
the same axis as the white. What effect does changing d have on the red
curve? Observe where the red curve crosses the x axis as you change the
parameters. What relationship do the roots of the red curve have to the
white curve?
