Real Analysis

By Prof. Surajit Borkotokey   |   Dibrugarh University
Learners enrolled: 1256
This course on Real Analysis is basically prepared for the Core course C 3.1 of the UGC prescribed syllabus on Mathematics non-Honours, however, it can be taken by learners with Mathematics Honours complementing to the Core course C 2.1 or even as a GE course by the learners with Honours in Physics, Economics, Statistics etc.
This course is designed to provide the learners an understanding of the analytical aspects of various mathematical objects pertaining to the set of real numbers. It covers the basic characterizing properties of real numbers, the sequence and series of real numbers and their convergence and finally, the sequence of real valued functions and their convergence. For pursuing any course on Pure and applied Mathematics or from other disciplines that involve analytical aspects of the Mathematical objects, this course is a must.
