Textbook in PDF format The greatest problem of math is that it is taught in the wrong way, that is, who teaches math several times doesn’t understand math or doesn’t know how to teach indeed, that is why math has a bad reputation and when we reach in subjects like calculus this gets even worse. If you try to learn any subject in the wrong way, it will be something bad, and this is not valid only for math. What happens is that people start throwing formulas and concepts without explaining from where they come from, what their origin is, for what they serve and if you take a subject half ways, you will not understand a thing. If you meet with your friends at a bar and sit down, you will not understand anything what they are talking about, because you missed the beginning of the conversation and with math is not different. Along the Years I developed my own teaching method about several topics, among them, the calculus one. So, in this book, I will talk about all the differential and integral calculus subject, in a simple and well explained way. I will make a revision about the most elementary part of math, and I will explain some extra concepts that you will need to know to understand calculus. Then, we will study limits, derivatives and integrals and once these concepts are consolidated, we will study differential equations and numeric calculus. Here in the book, I decided to unite everything that I learned about calculus in a single book. I think it is easier to explain in one time and go showing the sequence that calculus follows and the similarities and differences among the topics. So, here in the book you will find what I learned as calculus 1, 2, 3 and 4. Besides this, the idea of the book is to show how math and calculus can help you to grow in life, because math besides being an excellent tool, it will add a lot of logical thinking to you. I hope you enjoy the reading and thanks a lot for your attention!
