Tricky Integral (from a differential equation)

Hi,

I came across this integral in my exam the other day. I have spoken to other people and nobody was able to compute it.

The integral http://img171.imageshack.us/img171/2...0110615164.gif with respect to y

I tried by parts, and by substitution, maple and wolfram and I can't seem to do it!

Any ideas?

Re: Tricky Integral (from a differential equation)

While attempting the first homework set in the first course I ever took in differential equations, I was able to write the solution as an integral but simply was not able to do the integral. Finally, since this was a problem that had the answer in the back of the book, I looked there to discover that the solution was given in the form of an integral! Perhaps that is what is expected here.

I found out today that the integral was supposed to be $\displaystyle ${sin(\sqrt{y})$ $ which is pretty straightforward to integrate!

Thanks to everyone who tried that integral, I learnt something new (Rofl)
