Hi,
I'd like to ask why the first expression below takes so much longer to finish than the second. They look same to me.
\!\(N[â?«\_1\%â??\((x - 1)\)^ .5\ \(1\/\(1 + Exp[\((x -
2)\)/2]\)\) \[DifferentialD]x]\)
\!\(NIntegrate[\((x - 1)\)^ .5\ 1\/\(1 + Exp[\((x - 2)\)/2]\), {x, 1, â??}]\)
And I'd like to know if this apply to other numerical functions.
Thanks a lot,
Zheng
