13.1 Introduction

This chapter is an introduction to Calculus. Calculus is a branch of mathematics that mainly deals with the study of change in the value of a function as the points in the domain change. First, we give an intuitive idea of the derivative (without actually defining it). Then we give a naive definition of limit and study some algebra of limits. Then we come back to a definition of derivative and study some algebra of derivatives. We also obtain derivatives of certain standard functions.
