\n Formula Used:
\n If y = f(x), then ln(y) = ln(f(x))\n Differentiating implicitly: 1/y * dy/dx = [f'(x)/f(x)]\n So, dy/dx = y * [f'(x)/f(x)] = f(x) * [f'(x)/f(x)]\n

Logarithmic differentiation is a powerful technique in calculus used to find the derivative of complex functions that involve products, quotients, or powers of variables. Unlike standard differentiation rules, this method simplifies difficult expressions by taking the natural logarithm of both sides, transforming multiplication into addition, division into subtraction, and powers into multiplication.

This method is particularly useful when you encounter functions of the form y = [f(x)]^g(x), where both the base and the exponent contain the variable x. Attempting to differentiate such functions directly can lead to complicated chain rule applications. Logarithmic differentiation simplifies this process significantly, making it an indispensable tool for students and
