A formulae used for computing $?$ is given as following: $\frac{?}{8}=\frac{1}{1\times 3}+\frac{1}{5\times 7}+\frac{1}{9\times 11}?$ Write an M-file to use as many terms in the series to compute $?$ and plot a curve to illustrate that it takes a lot of terms to get fairly close to $?$. Determine how many terms are needed to compute $?$ correct to 7 decimal places.
