RATIONALE :
Engineering Mathematics is most important for engineering students. Without this subject, it
will very difficult to understand the other Engineering subjects.
Professional Mathematics is one of the subjects which is widely used in modern times. The
techniques of this subject are being applied in finding an approximate value, optimal value and
to develop the managing system in Industry. It will also help to develop attitude towards cost
effectiveness, selection of most effective alternative methods. The Mathematical technique and
modeling are so used in Industry, so it will not wrong to say that professional mathematics is an
industrial mathematics.
OBJECTIVES :
On completion of subject students will be able to

2.
3.
4.
The course will provide a student to develop
Managerial skill based on mathematical footing.
To understand the techniques and methods for Solving.
Engineering problems such as differential equations of higher orders in the fields of
Electrical circuits, LRC Circuits etc. using Lap lace transformation and others.
