This video looks at the solid of revolution constructing by rotating around line that is not an axis.
This 8-minute video lesson examines more volumes around the x-axis.
This video covers Finding the volume of a solid of revolution that is defined between two functions.
You know how to use definite integrals to find areas under curves. We now take that idea for "spin" by thinking about the volumes of things created when you rotate functions around various lines. This tutorial focuses on the "disc method" and the "washer method" for these types of problems.
This 9-minute video lesson uses the disk method around the y-axis.
This 10-minute video lesson provides an introduction to the divergence of a vector field.
This 11-minute video lecture examines the intuition of what the divergence of a vector field is.
This 11-minute video lecture analyzes a vector field using its divergence.
This video looks at the example of calculating the flux across a surface by using the divergence Theorem.
You know what the divergence theorem is, you can apply it and you conceptually understand it. This tutorial will actually prove it to you (references types of regions which are covered in the "types of regions in 3d" tutorial.
This video looks at breaking up the surface integral.
evaluating the surface integral.
This video covers more evaluation of the surface integral.
This video looks at Home stretch. Proving the Type i part.
This video looks at the divergent improper integral.
This video looks at the example where we do substitution twice to get the integral into a reasonable form.
This 10-minute video lecture provides an Introduction to the double integral.
This 10-minute video lesson on double integrals demonstrates how to Figure out the volume under z=xy^2.
This 8-minute video lesson on double integrals demonstrates how to integrate dy first!
This 9-minute video lesson demonstrates another way to conceptualize the double integral.
