Your syntax is wrong ....
Start with your kernel & give your variables numerical values:-
(hillb*((f0 + hilla)/(2*Pi*f*a*Cos[ArcSin[x/a]] + hillb))) - hilla /.
{hilla->3, hillb->50, f0->8, a->1, f->1}
Note differences between your pi & the way that functions are defined --
square brackets vs. round ones.
This kernel can be integrated using:-
Integrate[%, {x, -1, 1}]
which has a numerical value of:-
N[%]
Regards,
Dave.
