We push it to the limits

2. Find the region enclosed by y=2x from the
Warm-up
Find the region enclosed by y=2x from the
interval x=0 to x=3

3. Here is an idea of what I am talking about.
Today we will be rotating functions around lines and finding the volume of those rotations.
Here is an idea of what I am talking about.
