DIsplay the following and turn in printouts of the program and the results:
The number of terms needed to find pi/2
THe value of pi/2 using acos(-1.0)/2 using 10 digits after the deciaml point
The value of pi/2 found with the series using 10 digits after the decimal points (The first 6 digits after the decimal point sohuld match the value above.)
1+2 1+2+3 ==1+53+5+7
