Rationale
The Subject of Engineering Mathematics is being introduced into the Diploma Course to provide mathematical background to the students so that they can be able to grasp the engineering subjects, which they will come across in their higher classes properly. The course will give them the insight to understand and analyse the engineering problems scientifically based on Mathematics.
The subject is divided into two papers, viz. Engineering Mathematics  I and Engineering Mathematics  II. The curriculum of Engineering Mathematics  II consists of the following:
1. Calculus
2. Vector Algebra and Statics
3. Differential Equations
4. Dynamics
The details of the above broad topics have been provided in the curriculum.
Objectives
By covering the course in Engineering Mathematics  II, the students will be able to:

Know the basics of Differential and Integral Calculus, the meaning of limit, continuity and derivative of a single variable and their applications to engineering problems, the various methods of integration, how to solve simple ordinary differential equation of 1st and 2nd order, the concept of Vector Algebra, how to apply concepts of Vector Algebra to Statics, how to apply the concepts of Differential and Integral Calculus in solving the problems of Dynamics.

Understand their engineering application

Solve related simple numerical problems which will help them to understand the subject.
