VECTOR DIFFERENTIATION

Vector point function and Vector field: Let P be any point in a region ‘D’ of space.  Let r be the position vector of P.  If there exists a vector function F corresponding to each P,  then such a function F is called a vector function and the region D is called a vector field. Example:  consider the vector function Let P be a point whose position vector is At P , the value of F is obtained by putting x = 2, Y = I, z = 3 in…
