As said already, I cannot read the text in the photo reliably. Please post it as text. What have you tried so far? You cannot include an infinite number of elements in a sum, because this would take infinite time to run. So are ayou sure, that the sum converges?

n=1:1e6;%not quite infinate
It is the starting point to look for the zero crossing. You have to get close or else fzero will fail (goes to inf).
