- How do you change variables in double integrals?
- How do you use u and v substitution with a double integral?
- How do you find the area scaling factor when changing from dxdy to dudv?
- What is the Jacobian of a change of variables and how do you find it?
- How do you find the double integral of x^2y dxdy from 0 to 1 for x and y using a change of variables?
- How do you find the new bounds when you change variables in a double integral?

Change of variables in double integrals is discussed. This can really simplify a double integral, but it has to be done carefully. This process is described very well with some great example problems. The Jacobian is also discussed and examples are shown. The strength of this lecture is its useful example problems that are computed.

Very good video. Excellent examples with ample explanation.

Very clear and thorough explanations.
