Title: 11_5 The Chain Rule
Course: HELM Workbooks 2023-2024 > Section: HELM 11: Differentiation

In this Section we will see how to obtain the derivative of a composite function (often referred to as a `function of a function'). To do this we use the chain rule. This rule can be used to obtain the derivatives of functions such as \(e^{x^2+3x}\) (the exponential function of a polynomial); \( \sin( \ln x)\) (the sine function of the natural logarithm function); \( \sqrt{x^3 + 4}\) (the square root function of a polynomial).
