We are supposed to use substitution and integration by parts but I really don't know where to even start.

No matter what I substitute for U I will be left without a du.

[itex]\int cos(\sqrt{x})dx= \int 2ucos(u)du[/itex]

now you'll need to integrate by-parts....try using f(u)=2u and g'(u)=cos(u)du
