Introduction<br />
In this chapter the basic concepts of Differential Calculus of scalar functions are<br />
extended to vector functions.<br />
Here we study vector differentiation, gradient, divergence, curl, solenoidal <strong>and</strong><br />
irrational fields.<br />
Also we study about vector integration <strong>and</strong> verification of the integral theorems.<br />
