- Problem Set - A problem set with some problems from this lecture.
- How do you find line integrals, work, curl, exactness, and potentials in 3-dimensional space?
- How do you test if a field is a gradient field in 3-dimensional space?
- What is a test for gradient fields in three dimensions?
- For which a and b is axy dx + (x^2 + z^3)dy + (byz^2 - 4z^3)dz exact?
- How do you find curl F in 3D?
- What does curl mean geometrically for three dimensional objects?
The first few minutes of this lesson finish off some topics from last lecture. Then, line integrals, work, curl, exactness, and potentials are found for various objects in three dimensions now, instead of two. Again, this lesson builds on the analogous computations that we have seen so far as we move from two to three dimensions. Many examples are shown to make the ideas more concrete.
