Float Undefined Error...

Maple
I'm trying to numerically evaluate an integral using the evalf function, but I keep ending up with just the value "Float(Undefined)". After manipulating the expression in different ways I also get other error messages stating that something or value is too large. Can someone please help with this ? thanks, (worksheet attached in this message) Dan. Download 285_casimirEENG501HW5.mws
