Moreover, when f y ( x, y ) ≠ 0, one has y 1 ′ ( x ) = 1 − f x ( x, y ) f y ( x, y ) and y 2 ′ ( x ) = g x ( x, y ) 1 − g y ( x, y ), x ∈ I. (17) Note that f y ( x, y ) ≠ 0 since otherwise one would have f x ( x, y ) = 1 in (17) upon rewriting the first expression as f y ( x, y ) y 1 ′ ( x ) = 1 − f x ( x, y ) and thus a : = f x ( x ¯, y ¯ ) = 1, contradicting one of the hypotheses of the theorem.
