Theory of Real Function

By Dr. Anjaly Kishore   |   Vimala College, Thrissur, Kerala
Learners enrolled: 96
The course “Theory of Real Functions” is proposed for B.Sc. (Hons) Mathematics as the Core course. The course is an indispensable part of pure and applied mathematics which equip the undergraduate students to have a deeper and thorough understanding of the Functions of Real Variables and to apply the concepts of Limits, Continuity and Differentiability in real world problems. The course includes the introduction to Real Functions, Limits, Continuity, Uniform Continuity,  Differentiability, Intermediate Value Property, Mean Value Theorems, Taylor’s and Maclaurins’ Series expansions, Riemann integration and Improper integrals. The primary Learning Outcome of this course is Quantitative Reasoning, which is to understand and apply mathematical concepts, analyze and interpret various types and properties of Real Functions. The Learning Outcomes will be assessed through targeted questions - either the comprehensive final or an outside assignment. The applications of mathematics in various disciplines are seeking more analytical skills and deeper understanding of Real Functions. This course enable the  students who are interested in Economics, Physics, Engineering and Business Management to develop the skills in  analysing and solving  different types of functions of real variables which emerge in  mathematical modelling of real world problems.
