In summary, the conversation discusses the equality e^((ln(x))^2)=O(1) as x approaches zero and the possibility of manipulating infinities in this case. It is mentioned that x^2 does not equal O(x) when x approaches infinity but it does when x approaches zero. The conversation also explores the concept of g(x)=O(f(x)) and the limit of |g(x)/f(x)| as x approaches zero. The conclusion is that this limit is infinity, making it impossible for the equality to hold true.

Homework Statement


e^((ln(x))^2)=O(1)?
as x->0

Homework Equations


g(x)=O(f(x)) => |g(x)|<K|f(x)| as x->0 in this case but can approach any value as desired.
K<infinity

The Attempt at a Solution


We can try numbers for small x but non zero that satisfy the inequality however are we allowed to manipulate infinities? Somehow I think that the equality shouldn't stand.

I know that x^2 does not equal O(x) when x->infinity but does equal when x->0

We can look at it this way, g(x)=O(f(x)) => |g(x)|<K|f(x)| as x->0, K<infinity => lim x->0 |g(x)/f(x)| is finite.

The limit is infinity as x->0. How can this be O(1)?
 

1. What is an asymptotic relation?

An asymptotic relation is a mathematical concept that describes the behavior of two functions as their inputs approach a certain value. It is used to compare the rate of growth or decline of two functions and determine if they are approaching the same value.

2. How is an asymptotic relation different from an equal relation?

An equal relation means that two functions have the same output for every input, while an asymptotic relation only describes the behavior of the functions as their inputs approach a certain value.

3. What is the significance of an asymptotic relation in science?

Asymptotic relations are important in science because they allow us to make predictions about the behavior of a system as it approaches a limit. This can be useful in fields such as physics, biology, and economics.

4. How can I determine if two functions have an asymptotic relation?

To determine if two functions have an asymptotic relation, you can take the limit of their quotient as the inputs approach a certain value. If the limit is a constant, then the functions have an asymptotic relation.

5. Can an asymptotic relation change over time?

Yes, an asymptotic relation can change over time. This can occur if the functions have different rates of growth or decline, causing the relation between them to change as their inputs increase or decrease.
