Mathematics is the queen of all sciences. It is a tool that is used by engineers for expression of ideas and for communication of results. Mathematics plays a major role in Engineering as it is one of the major factors that determine how far engineers advance in their career. This book titled “Vector Calculus and Complex Analysis” written by Dr. P. Anuradha and Mr. V. Sudhakar is a good ......

Vector algebra deals with constant vectors (i.e.) vectors which are constant in
magnitude and fixed in direction. Vector calculus deals with variable vectors (i.e.)
vectors which are varying in magnitude or direction or both.

A single valued function f (z) is said to be analytic at a point z0, is it is differentiable at every point in some neighbourhood of z0. Analytic functions are also referred as regular or holomorphic functions.

A transformation is an operation which converts an expression into a simpler and
equivalent form. A transformation is employed to simplify the solution process of
a problem.
