An introduction to differential calculus.

  Author- K.Venkataraman  Differential calculus is an area of math that focuses on rate of change and slope. In this blog, I will try my best to give the reader a brief understanding of the concept and give solved examples for better understanding. In this blog, I have taken excerpts from the first and second chapter of “Differential Calculus for Beginners” by Joseph Edwards and it is my wish that the reader understands the concepts discussed.   Limits.   Before we start about differentials, we will have to know the notion of a limit. The limit of a function for an assigned value of an independent variable is such that the value of the function may be to differ as less as possible by making the value of the variable approach the value of the function.
