Important Topics for Class 11 Maths NCERT Solutions Chapter 13 Limits and Derivatives

Important Topics for Class 11 Maths NCERT Solutions Chapter 13 Limits and Derivatives are elaborated below:

  • Limits

Limits are values that a function (or sequence) approaches as the input (or index) approaches some value. Limits are important in calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals.

  • Derivatives

Derivative, in mathematics, is the rate of change of a function with respect to a variable. Derivatives are the basic solutions of problems in calculus and differential equations.

List of Limits and Derivatives Class 11 Formulas

  • d/dx [f(x) + g (x)] = d/dx [f(x)] + d/dx [g(x)]
  • d/dx [f(x) - g (x)] = d/dx [f(x)] - d/dx [g(x)]
  • d/dx [f(x) * g (x)] = d/dx [f(x)]*[g(x)] + [f(x)]*d/dx [g(x)]
  • d/dx [f(x) / g (x)] = {d/dx [f(x)]*[g(x)] - [f(x)]*d/dx [g(x)]} / g(x)2
  • limx → a(xn - an) / x - a = nan-1
  • limx → a sinx / x = 1
  • limx → a1 - cosx / x = 0
  • f ´( x ) = d f(x)/dx = limh → 0 [ f(x+h) - f(x) / h]
