CHAIN RULE Meaning and
Definition
-
The chain rule is a fundamental concept in calculus that describes how to differentiate the composition of two or more functions. It is primarily used to find the rate of change of a composite function, ensuring that the process is accurate and efficient. This rule is widely employed in various branches of mathematics, including differential calculus and differential equations.
In essence, the chain rule states that if one function is composed with another, the derivative of the composite function is the product of the derivatives of the individual functions. Mathematically, if y = f(g(x)), where both f and g are differentiable functions, then the derivative dy/dx can be expressed as dy/dx = dy/dg * dg/dx.
The chain rule can be best understood through an example: let's consider a function where y = f(u) and u = g(x). To find the derivative of y with respect to x, one must first find the derivative of y with respect to u (dy/du), and then multiply it by the derivative of u with respect to x (du/dx).
This rule is crucial when solving complex problems involving multiple functions, as it allows for the differentiation of functions that are significantly interrelated. By using the chain rule, mathematicians can determine the rate of change of composite functions and derive accurate results, enabling the study of various phenomena in fields such as physics, engineering, and economics.

Etymology of CHAIN RULE
The term "chain rule" in mathematics refers to a rule that helps calculate the derivative of a composite function. The etymology of the term "chain rule" can be traced back to the Latin word "catena", which means "chain" or "link". The concept of the chain rule is based on the idea that the derivative of a composite function is like unraveling a chain or following a linked sequence of functions. Thus, the term "chain rule" reflects the interconnected nature of the various functions involved in the calculus operation.
