I must really say that higher analysis with Mathematica 4.0 is full of traps! Just to inform you: During a (not too difficult) calculation I had to calculate Limit[SinIntegral[p*a],a->Infinity] After <<Calculus`Limit` I got as a result Pi/2. This is of course only correct iff p>0. For p<0 the correct limit is -Pi/2. -- Hendrik van Hees Phone: ++49 6159 71-2755 c/o GSI-Darmstadt SB3 3.162 Fax: ++49 6159 71-2990 Planckstr. 1 mailto:h.vanhees at gsi.de D-64291 Darmstadt http://theory.gsi.de/~vanhees/index.html
