 # Class 11 math introduces you too Calculus. Here, you will learn briefly about Functions, types of functions and a basic introduction to Differentiation, which is then continued in detail on my Class 12 math page.

## Introduction to Sets, Relations and Functions

You will learn about Sets, Relations and how a function is derived from a relation. You will understand the inter relation between each of these and why we learn about Sets before we learn about a function.
