Answer 2

Given:

The function is f(x,y)=xy

To Find:

Differential form of the function?

Step-by-step explanation:

• Since, we have the function that is given by f(x,y)=xy

• Now we can do the procedure the differentiate it

                          Let f(x,y)=z

• Then differentiate both side with respect to x we will get

                  $dz=\frac{dz}{dx} dx+\frac{dz}{dy} dy$

• we have z=xy put in above equation

                 $dz=\frac{d(xy)}{dx} dx+\frac{d(xy)}{dy} dy\\z=ydx+xdy$

Hence differential form is z=ydx+xdy.
