Worksheet 6 (3/2-3/6) (Download)
We've already know how to calculate the volume obtained by rotating f(x) about x-axis. Now, we would like to ask how to calculate the area obtained by rotating f(x) about y-axis. Intuitively, the area looks like cylinder geometrically. The second kind of questions is that if we have a particle moving along a curve which is given by an equation, can we describe how the particle moves?
