right.. now I post the entire solution since here again this doesnt work as well :-(

-(1/6)*(4*e+a^2*g*2^(1/2))^(1/2)*2^(1/4)*(-64*EllipticF((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))*e^4+2*EllipticF((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))*g^3*a^6*2^(1/2)*e+g^4*a^8*EllipticE((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))+8*EllipticF((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))*e^2*g^2*a^4+2*g^3*a^6*2^(1/2)*e*EllipticE((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))-16*g*a^2*2^(1/2)*e^3*EllipticE((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))-16*EllipticF((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))*g*a^2*2^(1/2)*e^3-8*g^2*a^4*EllipticE((g*a^2+2*2^(1/2)*e)^(1/2)*(-g*a^2+2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2), I*(8*e^2+g^2*a^4+4*g*a^2*2^(1/2)*e)^(1/2)/(8*e^2-g^2*a^4)^(1/2))*e^2)/((g*a^2+2*2^(1/2)*e)^2*g^(1/2)*(8*e^2-g^2*a^4)^(1/2))

I replaced E=e^2

(g*a^2+2*2^(1/2)*E^(1/2))^(1/2)*(-g*a^2+2*2^(1/2)*E^(1/2))^(1/2)/(8*E-g^2*a^4)^(1/2)

 

and this?

 

PS: Maple16 I'm using

(g*a^2+2*2^(1/2)*E^(1/2))^(1/2)*(-g*a^2+2*2^(1/2)*E^(1/2))^(1/2)/(8*E-g^2*a^4)^(1/2)

yeah of course the wronski or something is somehow wrong..:-( evaluating @ some explicit point like you did just shows the discrepancy which is also shown by the difference in the 2 plots... unfortunately I dont see an error... :-( thats why I wrote down the steps which I did...these are just a few...so I'm really surprised where the error lies :-(

/push ;)

Doesn't anyone have an idea :-(

jesus christ...thanks for your help@mark but sometimes you are just blockheaded... so no need for you to be cocky...

anyway

here is the function everything was comming from

from this i calculated the argument delta(k)=argument(yg)and then derived with respect to k

thats why the error arised...anyway...how can one ameliorate the behaviour for large k such that the integral int((delta(k)+Pi/2)*2*k/(k^2+4),k=0..infinity)can be evaluated...Integrating till 20/25 is unfortunately not exact enough

don't make me laugh?
