A Maple Problem

  1. Jul 29, 2009 #1
    Hi every body

    I am trying to intergrate the following function using Maple:

    j2out(x):=c2*x*exp(int((s-vout(s))/s/vout(s),s=0.0015..x));

    where vout(s)=0.07595560773650. C2 is constant

    but when I do, it returns a symbolic answers i.e Maple just returns the original expression without doing any thing even if I try evalf.

    Any suggestion out there?

    c2*x*exp(int((s-vout(s))/s/vout(s),s=0.0015..x));

    [tex]
    {\it c2}\,x{{\rm e}^{\int _{ 0.0015}^{x}\!{\frac {s-{\it vout} \left(
    s \right) }{s{\it vout} \left( s \right) }}{ds}}}
    [/tex]

    subs({vout(s)=0.07595560773650, c2=2.3456, x=1.92},%);

    [tex]
    4.503552\,{{\rm e}^{\int _{ 0.0015}^{ 1.92}\! 13.16558487\,{\frac {s-
    0.07595560773650}{s}}{ds}}}
    [/tex]

    evalf(%);

    [tex]
    3.279676846\;10^8
    [/tex]
