## Homework Statement

I have to find the solution of (1) and show that it is not unique if y(0) = 0.

I can prove it is not unique by using Picard's theorem but I don't know how to find the non trivial solution.

## Homework Equations

(1) y(t)' = Sqrt(y(t))

## The Attempt at a Solution

I don't know where to start... We have not seen how to solve nonlinear ODE's. A link to a technique or explanation to how to solve it would be very helpful. I'm not looking for the answer, I can get it with Mathematica... I want to understand how to get there.
