Section 1.5
In Exercises 1 and 2, we refer to a function f, but we do not provide its formula. However, we do assume that f satisfies the
hypothesis of the Uniqueness Theorem in the entire ty-plane, and we do provide various solutions to the given differential
equation. Finally, we specify an initial condition. Using the Uniqueness Theorem, what can you conclude about the
solution to the equation with the given initial condition?
