Say the only tool given to you is a calculator which performs addition, subtraction, multiplication, and division.
Let X= Summation (k=1 -->n) e^-(k/n)^2 with N^20
Explain a practical way of computing X within an error of 10^8. Roughly how big is X?
A Summation Series is used to Estimate a Quantity. The solution is detailed and well presented.
