Reciprocal Sketcher
Press play.
Move A.
The two curves are reciprocal functions of each other: when one of them has value 2, the other has value 1/2.
Special Missions
1. Use point A to draw a straight line that crosses the x-axis.
2. Use point A to draw a parabola tangent to the x-axis.
3. Use point A to draw a sine wave (oscillate between y-values 1 and -1).
4. Can you make the red curve look like a straight line?
