Definition: Linearising is a mathematical concept in calculus that refers to the process of transforming a function or an equation into its equivalent form with only one variable, often x. This transformation can be done by dividing both sides of the equation by a constant factor without changing the nature of the function. For example: 1. If you have the function f(x) = 3x^2 + 4x - 5 and want to linearise it into f(x) = ax + b, where a
