in reference to the definition prescribed in the maple help interface and the attached worksheet, i cant understand how hypergeom(n,d,z) handles empty values of the lists n,d eg hypergeom([],[],pi)  
 

> 

hypergeom([n[1], n[2], n[3], () .. (), n[p]], [d[1], d[2], d[3], () .. (), d[q]], z) = sum(z^k*(product(GAMMA(k+n[i])/GAMMA(n[i]), i = 1 .. p))/(factorial(k)*(product(GAMMA(k+d[j])/GAMMA(d[j]), j = 1 .. q))), k = 0 .. infinity)

please see the attached worksheet and assist me with understanding why these unusual results are computed.

simplify(op((diff(z/sqrt(z^2), [`$`(z, k)]))/pochhammer(1-k, k))[1]^(1/k), 'symbolic')
> 

simplify(simplify(op((diff(z/sqrt(z^2), [`$`(z, k)]))/pochhammer(1-k, k))[2]^(-1/k)-op((diff(z/sqrt(z^2), [`$`(z, k)]))/pochhammer(1-k, k))[1]^(1/k)*z, 'symbolic'))

I am trying but just one more question p...

procedure symbol
August 07 2017

what is the code to output every symbol assigned to a unique individual operator that is accepted by the maple interface, example what code can i assign to the function:

List_of_all_Operators_Available();

which will produce output in a list of single character strings

["*", "-","+","=",....]

invalid subscript selector error...
