It’s a great book and I’ve been using it to help me learn Calculus for a bit now. Sadly for some reason I was sent three of the same book so I’m selling two of the copies that I have. All three are in great condition so I hope the person who buys this book is genuinely happy with its contents! Great for an engineering student or anyone who is looking to learn mathematics on a deeper level by reading it. If I were you, use this book in tandem with a course especially something like khan academy for practice problems and the book can be great for reference.
