Yes it is. What I don't understand is why I get large

**negative** values instead of large

**positive** values for large values of n.

When I used the fact the the computer looks at the start-value

like it says:

, where

is the small error, I got this expression for

:

Which says that

should take large positive values when n is a large number. But the Python-program I made says that the larger the n, the more negative

becomes.

Therefore I suspect my program (see first post) is incorrect. I would really appriciate it if someone would help me what's wrong with it
