I copied directly from *Mathematica By Example* in PDF format, pg 220,
Revised First Ed.. I do not get the same result as the author. Does
any body else get ~pi ? I get 1.24012 for the numerical result, and
the same thing the book says for the symbolic result.
IN[ ]= value=Integrate[Cos[x^2-y^2],{x,0,Sqrt[Pi]},{y,0,Sqrt[Pi]}]
OUT [ ]= (Pi (FresnelC[Sqrt[2]]^2 + FresnelS[Sqrt[2]]^2 )) / 2
IN[ ]= N[value]
OUT[ ]= 3.14159
TIA
Steve
