Hi Jim, <snippage> > In Mathematica, Log is Log to base e, right (LN in excel)? > Did I use variables that have intrinsic functions in > Mathematica? Maybe I am misunderstanding the output with > regard to implicit parentheses etc. > Any help appreciated! 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.
