The Chain Rule is one of the most fundamental differentiation rules in calculus. It allows us to find the derivative of composite functions—functions built by combining two or more functions. Students, mathematicians, engineers, scientists, and economists often rely on the Chain Rule to simplify and solve complex problems.

In simple terms, the Chain Rule helps us differentiate a function inside another function. If we have a composite function like f(g(x))f(g(x)) f(g(x)), its derivative is: (f(g(x)))′=f′(g(x))⋅g′(x)(f(g(x)))’…
