The Subject 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 properly. This course will enable them to analyze and understand 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 - I consists of the following:
1. Algebra
2. Trigonometry
3. Co-ordinate Geometry
4. Computer Studies
The details are given in the curriculum.
Objectives
By covering the course in Engineering Mathematics - I, the students will be able to:
-
Know Sequence and Series, Permutations and Combinations, Binomial Theorem, Determinates and Matrices, Properties of Triangles, Solution of Trigonometrical equations, Inverse Circular functions, complex quantities, co-ordinate systems, equations of lines, circles, equations of lines in three dimensions, equation of plane, about the organization of computers, how to write algorithms, how to prepare flow charts and how to write programmes in BASIC to solve simple problems.
-
Understand their engineering applications.
-
Solve related simple numerical problems which will enable them to understand the subject.
