Find the first-order and second-order partial derivatives of the following functions: (x,y) =x2y3

Find the first-order and second-order partial derivatives of the following functions:

(x,y) =x2y3

Solutions

Expert Solution

Z = f(x, y) = x2y3

(1) First-order partial derivatives are:

Zx = Z/x = 2xy3

Zy = Z/y = 3x2y2

(2) Second-order partial derivatives are:

Zxx = /x(Z/x) = 2y3

Zyy = /y(Z/y) = 6x2y

Zxy = /y(Z/x) = 6xy2

Zyx = /x(Z/y) = 6xy2
