Homework Statement



[tex] \int \frac{sin(\sqrt{x})}{\sqrt{x}} dx [/tex]


Homework Equations





The Attempt at a Solution



I'm not too sure how to approach this. The only thing that rings a bell at this moment is

[tex] \lim_{x\to\0} \frac{sinx}{x} = 1 [/tex]

and I don't feel that it is of any relevance.

Thanks

Use the substitution u = √x. Whats du?

So [tex] du = \frac{dx}{2\sqrt{x}} [/tex]

[tex] 2 \int sin(u) du [/tex]

Cool, thanks.
