was doing study on Asymptotic Notations Topic, i recon that its formula is so simple yet it tells nothing and there are couple of things i don't understand.

When we say

f(n) <= c.g(n) where n >= n₀

And we don't know the value of c =? and n=? at first but by doing division of f(n) or g(n) we get the value of c. (here is where confusion lies)

First Question: How do we decide which side's 'n' has to get divided in equation f(n) or g(n)?

Suppose we have to prove:

2n(square) = O(n(cube))

here f(n) = 2(n(square)) and g(n)=n(cube)

which will form as:

2(n(square)) = c . n(cube)

Now in the notes i have read they are dividing 2(n(square)) to get the value of c by doing that we get c = 1;

But if we do it dividing n(cube) [which i don't know whether we can do it or not] we get c = 2;

How do we know what value we have to divide ?

Second Problem: Where does n₀ come from what's its task ?

Well by formula we know n >= n(0) which means what ever we take n we should take the value of n(0) or should be greater what n is.

But i am confuse that where do we use n₀ ? Why it is needed ?

By just finding C and N can't we get to conclusion if n(square) = O(n(cube)) or not. Would any one like to address this? Many thanks in advance.

Hi Everyone,

If anyone wants to get their Coursera certificate printed (and framed), noble frames is now helping with this. It's $9 and they add a gold seal. I've received 2 and they're really nice. Now I can show off my certificates :).

Anyone was curious about this during the class?

can not complete the Programming Assignment 2: Seam Carving, please help!

Hi guys, I have started a project to implement the algorithms found in these courses in python. Feel free to contribute to the github project at https://github.com/mihassan/python_algorithms #python #algorithm +Evaldo Junior +Wander Lairson

Quiet in this group

I am still busy with the last week of course 1, but i will continue with course 2. I really enjoy myself with this course!
