Solve the problem.For some inexact differential forms df, a function g(x, y, z) can be found such that dh = g(x, y, z) df is exact. When it exists, the function g(x,y,z) is called an "integrating factor". Show that g(x, y, z) =  is an integrating factor for the inexact differential df = -  dx +  dy +  dz.

What will be an ideal response?
