Following Goursat (1904, I, §15), for functions of more than one independent variable, the partial differential of y with respect to any one of the variables x1 is the principal part of the change in y resulting from a change dx1 in that one variable. The partial differential is therefore involving the partial derivative of y with respect to x1. The sum of the partial differentials with respect to all of the independent variables is the total differential WebQ: state and use the definition of the derivative explain how the derivative of a function is computed Q: Give a radical function and find its derivative using the basic theorems on differentiation.
