What is n 2 log 2 N?

Taking big O of the second function (ignoring constants), ( log n + 1) ( n 2 + 1) we get O ( n 2 log n). We can't really ignore the exponent. Expanding the first part, we get: The n 2 log 2 n term dominates all other terms, so we conclude that it is O ( n 2 log 2 n).

Does n converge if and only if p > 1?

Thus the series ? n = 1 ? 1 / n p will converge if and only if | 2 1 ? p | < 1, which happens if and only if p > 1 (why? Try to proving it just using the laws of exponentiation, and without using logarithms).

How do you determine if an = (1 + 1 n2)n converges?

How do you determine if an = (1 + 1 n2)n converge and find the limits when they exist? lim n?? an ? lim n?? e1 n = 1 and the sequence an converges.

Should I always choose O(n log n) over n 2?

Or can we say on an average n log n out performs n 2. If I want to make one of the algorithm as default sorting algorithm of my system then should I always choose O ( n log n) over O ( n 2) . Please give some input. No. Suppose sorting algorithm A takes 1000 n log ( n) steps and algorithm B takes n 2 steps and we need to sort 1000 elements.
