Linearization and Gradient Concepts

The video tutorial by Anil Kumar introduces the concept of linear law, which helps convert nonlinear equations into linear form. The tutorial covers four examples: y = 2x + B/X, y = C/X + D, y = PX^Q, and y = ae^(-KX). Each example demonstrates different techniques such as algebraic manipulation, reciprocal, and logarithms to achieve linearization. The video emphasizes understanding the process of converting nonlinear equations to linear form and plotting them to obtain a straight line.
