# Vector Calculus

Many quantities which are of interest in physics are both directed quantities (vectors) and can take on a continuous range of values, making calculus methods necessary. Several operations from the mathematical field of vector calculus are of particular importance in solving physical problems.

# Vector Calculus Operations

Three vector calculus operations which find many applications in physics are:

1. The divergence of a vector function 2. The curl of a vector function 3. The Gradient of a scalar function These examples of vector calculus operations are expressed in Cartesian coordinates, but they can be expressed in terms of any orthogonal coordinate system, aiding in the solution of physical problems which have other than rectangular symmetries.
