Applications of Mathematics in Electrical and chemical Engineering

Abstract

Mathematics or particularly applied mathematics is widely used in every engineering field. In this paper, several examples of applications of mathematics in mechanical, chemical, and electrical engineering are discussed. Applications here are the real ones found in the engineering fields, which may not be the same as discussed in many mathematics textbooks. The purpose of this paper is to relate mathematics to engineering subject. Many engineering students find it difficult to solve engineering problems which need mathematics a lot. The students have studied mathematics before (calculus, linear algebra, numerical analysis) but when they study engineering subjects which involve mathematics they often cannot relate mathematics to those subjects. It is hoped that through examples given, engineering students can be motivated to understand their engineering problems better. Also, it is expected that mathematics lecturers can be encouraged to provide mathematics problems which are more related to engineering fields.
