WebUsing Limits to Determine Big-O, Big-Omega, and Big-Theta. I am trying to get a concrete answer on using limits to determine if two functions, f(n) and g(n), are Big- O, Big- Ω, or Big- Θ. I have looked at my book, my lecture notes, and have even done some online research but I still haven't found anything that gives me a solid yes or no.

WebThe big/little O/Ω/Θ notation is not defined or, indeed, properly definable in terms of limits.
