## NCERT Solutions for Class 11 Maths Chapter 13 Limits and Derivatives – Brief Overview

1. Limits

A limit in mathematics is the value that a function approaches when its input approaches some value. Limits are used to define continuity, derivatives, and integrals in calculus and mathematical analysis. It is only because of its limitations, we can study a number from a distance.

• Few Properties of Limits

• limx→a c = c, where c is a constant quantity.
• The value of limx→a x = a
• Value of limx→a bx + c = ba + c
• limx→a xn = an, if n is a positive integer.
• limx→0−  1/xr = −∞, if r is odd, and
• limx→0−  1/xr = +∞, if r is even.
1. Derivatives

In mathematics, a derivative is the rate of change of a function with respect to a variable. Derivatives are essential for solving calculus and differential equation issues. Suppose f is a real-valued function and a is a point in its domain of definition. The derivative of f at a is defined by,

limh→0 [ f(a + h) – f (a) / h ]

provided this limit exists. Derivative of f(x) at a is denoted by f′(a).
