Has anyone heard about a way to find the sum of a serie of this form:
s=[tex]\sum_i{\exp(a+b\sqrt(i))}[/tex]
s=[tex]\sum_i{\exp(a+b\sqrt(i))}[/tex]

Why would you want to sum such a series?
Have you noticed you can take the "a" outside the ∑, and write it:
s = [tex]e^a\,\sum_n{e^{b\sqrt{n}}[/tex].

A series summation is a mathematical process of adding up a sequence of numbers in a specific order. It involves finding the sum of a series or adding together all the terms in a series.
The purpose of series summation is to determine the total value or sum of a series. It is commonly used in mathematics, physics, and engineering to solve problems involving sequences of numbers.
The two main types of series summation are finite and infinite. Finite series have a limited number of terms, while infinite series have an unlimited number of terms.
To perform series summation, you need to follow a specific formula depending on the type of series. For finite series, you can use the formula for arithmetic or geometric series. For infinite series, you can use the convergence test, such as the ratio test or integral test, to determine if the series converges or diverges.
Series summation is commonly used in various fields such as finance, statistics, and computer science. It is also used in physics to calculate the total energy of a system and in calculus to determine the area under a curve.
