Topics Covered in Exercise 5.5 Class 12 Mathematics Questions

Ex 5.5 class 12 maths chapter 5 is based on logarithmic differentiation which has been explained in detailed format by subject experts of eSaral. 


Logarithmic Differentiation

  1.  Logarithmic Differentiation

The process of utilizing logarithms to derive the derivatives of some complex functions is known as logarithmic differentiation. There are cases where it is easier to differentiate the logarithm of a given function than it is to differentiate the function itself. 

Logarithmic differentiation is a powerful technique to differentiate functions of the form 

                                  f(x) = [u (x)]v(x)

 Here both f(x) and u(x) need to be positive for this technique to make sense. 

By taking logarithm (to base e) the above may be rewritten as

                                  log y = v(x) log [u(x)]

Using chain rule we may differentiate this to get

$\frac{1}{y} \cdot \frac{d y}{d x}=v(x) \cdot \frac{1}{u(x)} \cdot u^{\prime}(x)+v^{\prime}(x) \cdot \log [u(x)]$

which implies that $\frac{d y}{d x}=y\left[\frac{v(x)}{u(x)} \cdot u^{\prime}(x)+v^{\prime}(x) \cdot \log [u(x)]\right]$
