Homework Statement
I have the integral
[tex]\int sin(2.13\sqrt{x}+2.4)\,dx[/tex]
I'm supposed to use the substitution [tex]y=2.13\sqrt{x}+2.4[/tex], aka. [tex]\sqrt{x}=\frac {y-2.4}{2.13}[/tex] to gain the following description of the integral:
[tex]\int sin(2.13\sqrt{x}+2.4)\,dx = E cos(y) + F\int y sin(y)\,dy[/tex]
I have obviously not tried every method possible, but I'm running out of ideas on how to proceed on this one. I tried using the quotient rule without any good looking results, probably due to my non-existing knowledge about these mathematical methods. Any help would be appreciated!
