RADIAN AND STERADIAN: Radian: The radian is the measure of a plane angle. One radian is defined as a plane angle with its vertex at
INTEGRAL THEOREMS Gauss’s Divergence Theorem: Statement. It states that the volume integral of the divergence of a vector field A, taken over any volume, V
DIVERGENCE OF A VECTOR FIELD In the previous article, we have discussed del operator and gradient. Today, we will discuss another two operations of del
DEL OPERATOR Vector differential operator `del’ is represented by a symbol . Its another name is `nabla’. For three dimensional case, it is defined as
