Part of a two-volume series, "Allied Mathematics Volume I" specifically cater to the students in the universities of Tamil Nadu. Succinctly written, it is designed in such a fashion to help in better understanding of students. Concepts have been explained, working rules to solve problems are given in specific subrules and the formulae involved in each solution are given in appropriate places of the solution. Also, Madras university questions have been used in the relevant places to illustrate the different concepts while chapter-end exercises with hints add ably to the practice quotient.
