Hi all, Can someone please explain why the summation is equal to N, when infinity = 1 ? I do understand that it is equal to 1^0 + 1^1 + 1^2 + ...... + 1?N-1 , but why is it equal to N? Thanks in advance.
Because it is math? If N=1, Then N-1=1-1=0, Then Sum=1^0=1, Therefore 1=1 and N=Sum If N=2, Then N-1=2-1=1 Then Sum=1^0+1^1=1+1=2, Therefore 2=2 and N=Sum If N=3, Then N-1=3-1=2 Then Sum=1^0+1^1+1^2=1+1+1=3 Therefore 3=3 and N=Sum There is one thing that is missing. There should have been a condition placed at the start of the excercise. This condition is: N>n (N is always gretater than n) or N-1=>n (N minus 1 is equal or greater than n).
