Answer 2

Step-by-step explanation:

Partial differential equations can be obtained by the elimination of arbitrary constants or by the elimination of arbitrary functions.

By the elimination of arbitrary constants

Let us consider the function

f( x, y, z, a, b ) = 0 ------------- (1)

where a & b are arbitrary constants

Differentiating equation (1) partially w.r.t x & y, we get
