Theorem 1- Existence of a Unique Solution
Consider the initial value problem (IVP) 2 = f (x, y) , y (xo) = Yo- Let R be a rectangular region in
Ty plane defined by a < ¤ < b,c < y < d that contains the point (#o, Yo) in its interior. If f (x, y)
af
are continuous on R, then there exists some interval Io : ¤o – h <x < To + h, h > 0
and
contained in a < I < b, and a unique function y (x), define on Ig, that is a solution of the given IVP.
Given f (x, y) = (y² – 9) 3. Examine which of the given points possesses a unique solution
according to the Theorem 1?
