Objectives 1 Given a density function, find the mass, center of mass, moments of intertia of a thin plate. 2 Given a probability distribution function, calculate probabilities and expected values. Lecture 14: Applications of Double Integrals
Integral of density Suppose that we have a thin plate (lamina) described by a region R . Let ρ ( x , y ) be the density of the plate at a point ( x , y ). We define the mass to be m = Z Z R ρ ( x , y ) dA Lecture 14: Applications of Double Integrals

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
