Lecture Description

Using line integrals to find the work done on a particle moving through a vector field.

Course Description

Topics covered in the first two or three semesters of college calculus. Everything from limits to derivatives to integrals to vector calculus. Should understand the topics in the pre-calculus playlist first (the limit videos are in both playlists).
