The chain rule can also be expressed as:
The chain rule can also be expressed as:
:<math>\frac {dy}{dx} = \frac {dy} {du} \times \frac {du}{dx}.</math>
:<math>\frac {dy}{dx} = \frac {dy} {du} \times \frac {du}{dx}.</math>
The chain rule can also be applied to multivariable functions. The derivative of a multivariable function is expressed as follows:
<math> \frac {d}{dt}(f(x(t), y(t))) = \frac{\partial f}{dx}\times \frac{dx}{dt} + \frac{\partial f}{dy}\times \frac{dy}{dt} </math>
