1. The problem statement, all variables and given/known data Check if the given initial value is a unique solution. 2. Relevant equations y'=y^(1/2), y(4)=0 3. The attempt at a solution I got y(t)=(t/2)^2 and 0 at t=4 So, we have two solutions to i.v.p.; therefore, it's not a unique solution. Is it correct?
