The book which can be referred to for ‘basic mathematics’ of physics of class 11 to clear all doubts is the book “Chapter-wise NCERT + Exemplar + Practice Questions with Solutions for CBSE Physics Class 11”. This book is divided into 3 parts. Part A has solutions (question-by-question) of all the questions/exercises given in the NCERT textbook. Part B has solution to questions given in the NCERT Exemplar book. Part C has selected questions for practice required in class 11 examination along with solutions.

The solutions are structured in such a way that all the concepts get cleared by the students.
