Topics Covered in RS Aggarwal Solutions for Class 12 Chapter 10 – Differentiation

Differentiation of Inverse Trigonometric Functions:

  • Differentiation of sin-1 x with respect to x is 

Where x ϵ (-1, 1)

  • Differentiation of cos-1 y with respect to y is 

Where x ϵ (-1, 1)

  • Differentiation of tan-1 x with respect to x is 

Where x ϵ R

  • Differentiation of cot-1 x with respect to x is 

Where x ϵ R

  • Differentiation of sec-1 y with respect to y is 

Where x ϵ R – [-1, 1] 

  • Differentiation of cosec-1 x with respect to x is 

Where x ϵ R – [-1, 1] 

Differentiation of Exponential and Logarithmic Functions:

Differentiation of a Function of a Function:

Theorem: For any two differentiable functions f(x) and g(x), fog is also differentiable and

(fog)’ (x) = f ’(g (x) ). g ’(x).

Relation between  dy/dx and dx/dy :

Logarithmic Differentiation:

  • In this section, we will learn to find the derivatives of the functions of the form

     [f(x)] g(x)

We do this by taking the logarithm of both sides and the differentiating both sides.

If y = [f(x)]g(x)

y = [f(x)]g(x) =  eg(x).log {f(x)}

Differentiating of Infinite Series:

Sometimes the value of y is given as an infinite series and we are asked to find dy/dx. In such cases, we use the fact that if a term is deleted in an infinite series, it remains unchanged.

Differentiation of Parametric Functions:

Differentiation of Determinants:

Highlights:

For continuous functions:

  • f(x) + g(x) will be continuous at x = a
  • f(x) – g(x) will be continuous at x = a
  • f(x) × g(x) will be continuous at x = a
  • f(x) / g(x) will be continuous at x = a; provided g(a) ≠0
  • d .[f(x)+g(x)] / dx = d . f(x)/dx + d . g(x)/dx
