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 y0 D f .x; y/ exists on some open interval I containing the point x D a and, moreover, that if in addition the partial derivative @f =@y is continuous near .a; b/, then this solution is unique on some (perhaps smaller) interval J . In Problems 11 through 20, determine whether ex- istence of at least one solution of the given initial value prob- lem is thereby guaranteed and, if so, whether uniqueness of that solution is guaranteed.
