This applet dynamically illustrates how rotating an arc length of a piece of the graph of a function , from to , about an axis, generates a surface of revolution.
For simplicity, the axis of revolution here is the x-axis.
You can alter the values of
= lower limit of integration
= upper limit of integration
= number of equal intervals into which the interval is divided.
How does increasing the value of change the appearance of the surface of revolution?
