It is a very helpful book for JEE Advanced, I myself used this for my JEE preparation. Before buying this book I was very much afraid of the graphs and my teacher also used to tell us innovative approaches to solve conventional problems easily using graphs it made me more anxious, I thought ‘if this scenario continues I will surely loose my grip from mathematics(especially calculus)’ . Then one of my senior suggested me Play with graphs, I started practicing the starting was very smooth as the book started with basic graphs like logarithmic, trigonometric,exponential functions and then it took to me complex graphs which are actually combinations of basic graphs i.e. they contain 2 or more than 2 functions.

After continuous practice I actually started playing with graph .

Thanks for reading.
