1. The problem statement, all variables and given/known data lim ( 1 - ( - x ) ^ n ) / ( 1 + x ) as n -> infinity 2. Relevant equations I can't understand why this equals to 1 / ( 1 + x ) (No matter what power of " n " was x e.q: x ^ 2n or x ^ ( n ^ 2 ) 3. The attempt at a solution I have no clue what rule to apply. I thought it might be a case of using the lim ( 1 + 1 / n ) ^ n to get to " e " but this seems like a non-sense in this case.
