Hi
Integrating
gives
Derivation with respect to y gives
But
Therefore
and f(y,z) = yz + g(z)
The same approach for z leads to
I have the following from Vector Calculus:
I have to determine whether this system has solutions or not. If there is a solution I have to find it. I also have to determine the domain on which solution is defined. Also some words about uniqueness must be said...
Can anyone give me some help?
