• Day 33 – February 21, 2013• Section 12.2: Review Fubini’s Theorem• Section 12.3: Double Integrals over General
Regions
Compute the volume below z = f(x,y) and above the rectangle R = [a,b] x [c,d]
To be able to compute double integrals we need the conceptof iterated integrals.

Section 12.3: Double Integrals over General Regions
Problem: Compute the double integral of f(x,y) over the region D shown in the diagram.
It turns out that if we can integrate over 2 special types of regions,
Section 12.3: Double Integrals over General Regions
Problem: Compute the double integral of f(x,y) over the region D shown in the diagram.
It turns out that if we can integrate over 2 special types of regions, then properties of integrals implies we can integrate over general regions.
