We can use this series

$e=1+\frac{1}{1!}+\frac{1}{2!}+\frac{1}{3!}+\frac{1}{4!}+$dots

to compute $e,$ that is the Euler number.

Write an M$-$file to calculate the value of $e^3$ using the given series. See how many terms are needed to get $6-$figure agreement with the MATLAB build$-$in function exp$(3).$
