The cosine of an angle can be computed from the following infinite series:

cosx?1?x2 ?x4 ?x6 ?........ 2! 4! 6!

Write a program that reads an angle x (in radians) from the keyboard. Then, in a function compute the cosine of the angle using first five terms of the series. Print the value computed along with the value of the cosine computed using the C++ library function.
