Partial Derivative | Multivariable Chain Rule

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). In this tutorial, we are going to look on to functions of other functions (Multivariable) using chain rule through dependency graph. If U = f(x,y) and x and y jointly depend on g(r,α), The partial derivative of U with respect to r. δu/δr = (δu/δx)*(δx/δr)+(δu/δy)*(δy/δr) If you find this video interesting, kindly subscribe to my channel for more exciting Maths tutorials.
