The value for PI can be determined by the series equation

PI=4x(1-1/3+1/5-1/7+1/9-1/11+1/13-....)

write an interactive program that asks the user how manu terms of series

equation to use in approximating PI. Then calculate and display the

approximation. Here is a sample run:

PI Approximation Program

How many terms of the series should be included?

(The more terms, the better the approximation)

=> 3

Approximation value of pi is 3.466667.

Don't you mean ~3.1415 ... ??

Jump to PostI hope he does, 3.4 is a tad bit off .... hey try to do the project on your own and when you get absolutley then specify your exact problem and post some code then we can help you out :D

Jump to Postyou need to display pi when it has been approximated:

`cout << "approximate value of pi is"<<pi<<endl;`

and`pi =4x(1-1/3+1/5-1/7-+1/9-1/11+1/13/...);`

will not work becuase the compiler can not calculate the ... so to coninue you would need some sort of looped structure. Then when it has done that, …
