This is a book of notes and formulas which contains concept clearing notes and formulae with examples. It is based on CBSE syllabus for class XII Maths and CUET syllabus of entrance exams for undergraduate programmes. It covers the following chapters of class 12 & CUET mathematics: Relations and Functions, Inverse Trigonometry, Matrices, Determinants, Continuity, Differentiability, Application of Derivatives. To use it as study guides, topics are explained with the help of examples and figures. For the students to remember the formulae easily, a formula is written first and then it is explained, if needed, with the help of well labelled figure. After that, an example is given to know how to apply it. All chapters are arranged as in NCERT textbook for easy reference while finding solutions of NCERT exercises. The book is written just like a student makes notes in the class to remember the things easily. Pointers are given to grasp and memorize points on the topics just like in notes writing. It makes the book very helpful to learn and remember all concepts even though they do not contain questions for practice. Also, it becomes very useful while revising for exams. I hope the students will be able to understand each and every concept comfortably through this book.class 11, formulas, notes, CBSE, CUET
