Question

problems
form the partial differential Er from

Z= yf(x)+ xg(y)​

Answer 1

Answer:

i do not have any idea about this.

Answer 2

Actually you are supposed to represent partial differentiation by 'dou' but in this app it is not possible, so i will use d() instead.

$\frac{dZ}{dy} =f(x)\frac{dy}{dy} +x\frac{d(g(y))}{dy}$

$\frac{dZ}{dy} =f(x)+x\frac{d(g(y))}{dy}$
