Both are important in calculus as it helps to develop the higher-dimensional of the fundamental theorem of calculus. Generally, divergence explains how the field behaves towards or away from a point.

Web8 Index Notation The proof of this identity is as follows: • If any two of the indices i,j,k or l,m,n are the same, then clearly the left-hand side of Eqn 18 must be zero.

For a function in three-dimensional Cartesian coordinate variables, the gradient is the vector field: As the name implies, the gradient is proportional to and points in the direction of the function's most rapid (positive) change. For a vector field written as a 1 × n row vector, also called a tensor field of order 1, the gradient or covariant derivative is the n × n Jacobian matrix:
