Hi,

I try to calculate a contour integral(in fact it is the contour integral defined in the principle argument theorem) with a function that was given in my earlier entry here

y:=2.0;W:=(2^(z+3/2)*Pi)/(GAMMA(-z/2)*GAMMA(1/2-z/2)):V:=1.0;
  f:=1+((abs(V))^2/W^2)*(CylinderD(z,y)^2)*(CylinderD(z,-y)^2-CylinderD(z,y)^2);
 

I try to use this f in this contour integral as:

phi:=t→exp(I*t);

g:=(diff(f(phi(t)),t)/f(phi(t))) * diff(phi(t),t);

here I give f ` (z)/f(z) is g. And

 

Hi all,

I was wondering how I would introduce the generalized hypergeometric function command in maple ? This is  like HypergeometricPFQ[ {{1 - \[Nu]/2}, {1}, {1, -(\[Nu]/2)}}, {{2, 3/2}, {}, {1 - \[Nu]/2}}, z^2/2, z^2/2]  in Mathematica but when I try to give it in maple I get error messages...

Thanks!

Hello,

I`m a new Maple-user and I have some troubles with finding real zeros of a complex function/equation. Suppose that I have let me say CylinderD(n,a)*CylinderD(n,I*a)+exp(I*n*Pi/2)=0 , where a =2.0 and I=sqrt(-1)  and I want to find out the real zeros for this equation. I can count the zeros by using Rouche theorem and argument principle but I need more. Also, I tried to find the roots of a function CylinderD(n,I*a) by using maple and I couldn`t obtain it. Do you have an idea ? Thank you for your help.
