Hi thank you for your video. To prove big Theta, do I have to prove big O and big Omega and if both are true big Theta is proved? Also could you tell me following: The way to find a constant c, we are choosing the one that we are trying to proove (for example xxx = O(n²). So on the right side of "is larger or equal than) all of the values will have to be larger than on the left side but max. as n². What happens if we cannot choose a larger one by this definition? So if it is 100n³ = O(n²) we cannot choose n² as the largest. Many thanks from Germany!!

Hi could I ask what n not is? In our class we use C and K but I find your method to be easier.

@QuocDatPhung

N not is the same as k :) some textbooks use different variables but they mean the same thing! Also I'm really glad to hear that you find my method easier! I would really appreciate if you could kindly share or subscribe ~ you can find all of my CS videos in this link: kzread.info/head/PLeTO6OT3-FKmuxOu4RtupTay1yrMp6QGC

For the 5n^2 + 3nlogn + 2n + 5 is O(n^2) I got constant C = 12 because instead of raising nlogn to n^2 I just dropped it all together 5n^2 + 3nlogn + 2n + 5

Don't you think c^n is bigger than n^c

@QuocDatPhung

Ай бұрын

Yes, in the video I said that c^n is bigger than n^c at 5:20

howd you get 2n + 3n

Hi Timmy, please let me know the timestamp of the question you're referring to.

@QuocDatPhung

4 ай бұрын

Do you mean the one at 1:12? Ok, now imagine you're in a math class. Let's say you have f(x) = x and g(x) = x^2. Since g(x) is quadratic, and f(x) is linear, then it must be that g(x) > f(x) meaning g(x) will at some point intersect f(x) and be above it forever. Agreed? You can also pick g(x) = x^3 or whatever you want and g(x) is still greater than f(x). Now, coming back to 1:12, let's say f(x) = 2n + 3. Can we find a function greater than this one? Yes. We can say the function 2n + 3n or 2n^2 + 3 or whatever you want. But for the sake of simplicity, let's pick 2n + 3n. Therefore, you get 2n + 3 < 2n + 3n. Does that make sense? Don't overcomplicate it. It's easier than it looks.
