Why in this code:
>> r,a,n,i,noo=var('r,a,n,i,noo')
>> hterm(a,r,n) = 1/(a^2+(r+n)^2)^(3/2)
>> h(a,r,noo) = a^2*sum(hterm(a,r,i), i, 0, noo)
>> print h(a=1,r=0.0123,noo=oo)
sum((i^2 + 0.0246*i + 1.00015129)^(-3/2), i, 0, +Infinity)
>> print h(a=1,r=0.0123,noo=10)
sum((i^2 + 0.0246*i + 1.00015129)^(-3/2), i, 0, 10) #SUMATION
but if I do
>> sum((i^2 + 0.0246*i + 1.00015129)^(-3/2), i, 0, 10)
1.49935960541
How can I turn the #SUMATION to a number when I call function h?
Thanks
Pedro Cruz
