Euler's method for the numerical integration of an ODE IVP uses the stepping formula:

You are given and that , so immediately the stepping formula will tell you the value at , then applying it again from and the value of you found from the first step, it will give the value at .

I am getting bigger and bigger numbers... Is it supposed to blow up like that?

No, it shouldn't. Please show what you have done and why you are getting "bigger and bigger numbers".

Yeah. I knew the solution to the equation already.

Thanks for the help. I appreciate it. And this was a test question... I just wanted to get clarification on the answer.

But the next question was the same thing with the Improved Euler's method and I got a much better answer, which would mean that bigger values of h are allowed in the Improved method as opposed to the classical method. - March 4th 2009, 07:19 AMCaptainBlack
