Differentials of 2 Variable Functions
Suppose there is a 2-variable function z=f(x,y). Then we say that the differential dz is:
Differentials of 3 Variable Functions
Of course, differentials can be extended to 3-variable functions as well. Suppose there is a 3-variable function w=g(x,y,z). Then we say that the differential dw is:
Differentials of 2 Variable Functions
Suppose there is a 2-variable function z=f(x,y). Then we say that the differential dz is:
dz=fxdx+fydy
Differentials of 3 Variable Functions
Of course, differentials can be extended to 3-variable functions as well. Suppose there is a 3-variable function w=g(x,y,z). Then we say that the differential dw is:
dw=gxdx+gydy+gzdz
