If you are starting with the course, then you may buy the books in the Miscellaneous Section only. Later, your faculty will prescribe other books in class. A word about Solution Manuals: No one learned Mathematics by reading solutions. Instead, try sequential... by Ashani Dasgupta

This is a Test of Mathematics Solution (from ISI Entrance). The book, Test of Mathematics at 10+2 Level is Published by East West Press. This problem book is indispensable for the preparation of I.S.I. B.Stat and B.Math Entrance. Also see: Cheenta I.S.I. & C.M.I.... by Ashani Dasgupta

A.M.- G.M. Inequality can be used to prove the existence of Euler Number. In this discussion, we venture into the fascinating journey from classical inequalities to modern real analysis. Watch the video A short code in Python to check boundedness of a classical... by Ashani Dasgupta

Hello mathematician! I do not like homework. They are boring ‘to do’ and infinitely more boring to ‘create and grade’. I would rather read Hilbert’s ‘Geometry and Imagination’ or Abanindranath’s ‘Khirer Putul’ at that time. Academy Award winner Michael... by Ashani Dasgupta

Why should we study real analysis? Once you are inside the first course of this beautiful subject, you will find hundreds of complicated theorems and formulas floating around the canvas. What makes this journey into rigorous deductive reasoning interesting is: we get... by Ashani Dasgupta

The golden ratio is arguably the third most interesting number in mathematics. The first two slots are of course reserved for \( \pi \) and \( e \). Among other things, golden ratio has the uncanny habit of appearing unexpectedly in nature and geometry. What is golden...
