y(0) = 1
y'(0) = 0

Homework Equations

The Attempt at a Solution

No idea how to use it.
If I use the substituion y' = p, and y'' = p'p I need to integrate e^{y^2} which is unintegratable. What should I do?

According to your DE and initial conditions, what is y&#039;&#039;(0)? How about \left.\frac{d^n y}{dx^n}\right|_{x=0} ? What might you expect the solution to be if all the derivatives are zero at some point? Can you prove that is the only solution?

I get what you're trying to say - that the solution is y=1.
I don't know how to prove it though.
