The chain rule is used to find the first order partial derivatives of a function in terms or two variables. Take the derivative of each variable separately when taking the derivative of a multivariable function.
We can take the partial derivative of a function with respect to a particular variable by treating all other variables as constants. In the context of derivatives, a "constant" is a value that does not change as the function changes.
The presenter addresses the different types of derivatives when solving for a partial function.
To evaluate a partial derivative at a particular point, plug in the point's coordinates for x and y in the equation for the partial derivative.
