Remember this is a workbook. It presents formulas, some worked out examples and then leaves u with some unsolved problems. Answers to each and every problem has been given at the end which is useful. In calculus there are bound to be multiple answers to a problem and they have been addressed too which is to be appreciated. Don’t expect proofs for the formulae. This book is not intended to be didactic.<br>If u r a beginner, go through the formulas, worked out examples and then try to do exercises without out seeing the solutions. Even if u see the solution, don’t see the whole solution, instead see it only line by line working out on ur own as much as possible.<br>If u know the basics, try doing the exercises straight away and enjoy<br>If u r a professional, this book is not for u<br>Thanks Chris
