Quote:Whether you are a high school student or a freshman in college or just an ordinary person, if you are interested in learning calculus you need to bury your face in my book. Read it at least 10 to 15 times, back and forth! There are a lot of questions which you are challenged to solve. Have fun with that!

This is the fourth volume of a series that covers the base-line knowledge you need to go deep into calculus. These topics include "Tangent Lines on Functions", "Concept of Derivatives", "Discussion on Types of Discontinuities of Functions", and much more. Just enjoy reading through the book and make sure to solve all the questions and problems. Don't leave anything behind. So, stop wasting time and start reading the book! Good Luck...
