Vector calculus is a field of mathematics concerned with multivariate real analysis of vectorss in 2 or more dimensions. It consists of a suite of formulas and problem solving techniques very useful for engineering and physics.

We consider vector fields, which associate a vector to every point in space, and scalar fields, which associate a scalar to every point in space. For example, the temperature of a swimming pool is a scalar field: to each point we associate a scalar value of temperature. The water flow in the same pool is a vector field: to each point we associate a velocity vector.

Three operations are important in vector calculus:

Most of the analytic results are more easily understood using the machinery of differential geometry, for which vector calculus forms a subset.
