Chapter 6, Problem 6.14PE

(Estimate π) π can be computed using the following summation:

     $m\left(i\right)=4\left(1-\frac{1}{3}+\frac{1}{5}-\frac{1}{7}+\frac{1}{9}-\frac{1}{11}+\cdots \frac{{\left(-1\right)}^{i+1}}{2i-1}\right)$

Write a method that returns m(i) for a given i and write a test program that displays the following table:

i	m(i)
1	4.0000
101	3.1515
201	3.1466
301	3.1449
401	3.1441
501	3.1436
601	3.1433
701	3.1430
801	3.1428
901	3.1427
