if anyone knows what i am talking about say "I".

gamma2(infinite)*x2*exp(J1(2)*x2+J2(2)x2^2+...+Ji(2)x2^i)

that's kind of hard to interpret, but i can scan in the equation if anyone might have a remote idea

and no this isn't asking for HW help... this is just for fun

actually i figured it out...

keep gamma2(inf) and x2 out of the expansion

expand exp(x) as 1 + x + x^2/2 + x^3/6 + ....
put the Ji(n) terms in front of it.. multiply the x2 in multiply the gamma term in.. BAM!

thanks for the help

It's differential eqations - as he said before. A lot of fluid and thermodynamics stuff uses eqations and operations like that.

Oh, the work I look forward to....
