Question
A more detailed version of Theorem 1 says that, if the function
f(x, y) is continuous near the point (a, b), then at least one so-
lution of the differential equation y = f(x, y) exists on some
open interval I containing the point x = a and, moreover, that
if in addition the partial derivative af/ay is continuous near
(a, b), then this solution is unique on some (perhaps smaller)
interval J. In Problem
determine whether ex-
istence of at least one solution of the gven initial value prob-
lem is thereby guaranteed and, if so, whether uniqueness of
that solution is guaranteed.
