I bought this book to brush up on my graphing skills as it had been a while since I learnt these concepts. I found this book to be an excellent resource for all the basic “graphing musts”. It is not intimidating as a math textbook and yet provides all the necessary foundational concepts that one needs to know to plot and interpret graphs. It has an abundance of worked out examples and it also has plenty of unsolved exercises for the learner to practice. The answers to all the unsolved problems made it possible for me check my understanding as I solved the problems. I would absolutely recommend this book to anyone who is interested in mastering the graphing skills.
