As to whether or not this solution (or rather, a family thereof) is unique, I expect it to be so if we require continuity, but that's another story. Share.Feb 9, 2016 · The meaning is clearer if you introduce a function that only explicitly depends on the independent variables: g(x, z) = f(x, y(x, z)) g ( x, z) = f ( x, y ( x, z)). Then you mean ∂g ∂x ∂ g ∂ x, which is still a partial derivative (since z z is held constant), even though g g depends on x x in two different ways. By contrast if you had. y is a variable, while f (x) means "the value that f maps x to"; the equation y=f (x) could be read as "y equals the value that f maps x to" or more succinctly as "f maps x to y". 1.
