Nettet29. jun. 2024 Β· In this case it does: the numerator n 2 + 1 βˆ’ n 2 + n is negative, since n 2 + n is bigger than n 2 + 1, but so is the denominator, since n 3 + n 2 + 1 is bigger than n 3 + 1, hence their ratio is positive, so the limit is non-negative, which agrees with the sign of the answer I got. Instead, write n 2 + 1 = n 1 + 1 n 2, and similar for ... NettetFind the limit of square root π‘₯ plus nine minus square root minus π‘₯ plus nine over π‘₯ as π‘₯ approaches zero.
