MA2111 ENGINEERING MATHEMATICS(Common to all branches of B.E. / B.Tech. Programmes)
AimThe course is aimed at developing the basic Mathematical skills of Engineering students that are imperative for effective understanding of Engineering subjects. The topics introduced will serve as basic tools for specialized studies in many Engineering fields, significantly in fluid mechanics, field theory and Communication Engineering.
ObjectivesOn completion of the course the students are expected
- to identify algebraic eigenvalue problems from practical areas and obtain the eigensolutions in certain cases.
- To understand solid geometry concepts
- to understand maxima and minima concept.
- to solve differential equations of certain types, including systems of differential equations that they might encounter in the same or higher semesters.
- to understand double and triple integration and enable them to handle integrals of higher orders.
- to know the basics of vector calculus comprising of gradient, divergence & curl and line, surface & volume integrals along with the classical theorems involving them.
- to understand analytic functions and their interesting properties.
- to know conformal mappings with a few standard examples that have direct application.
- to grasp the basics of complex integration and the concept of contour integration which is important for evaluation of certain integrals encountered in practice.
- to have a sound knowledge of Laplace transform and its properties.
- to solve certain linear differential equations using the Laplace transform technique which have applications in other subjects of the current and higher semesters.
