The second one is a limit, the limit of the expression you described is 1 as the second term (1/n) approaches 0 as n approaches infinity.

Secondly 1 + 'The sum of the reciprocal of all natural numbers' is infinite, and that's very well established. Did you mean (1/i!) instead of (1/i)?

I'm talking about the expressions not the code.

Ah I wasn't certain what you meant,

Sorry for the confusion, it is supposed to be n! and i!. Don't know how that got by me

Thanks for clearing that up
