In summary, limits as x approaches a certain value, such as infinity or 0, can be defined using the concept of getting closer and closer to that value. For example, if we say lim x→0 f(x) = ∞, it means that for any large number M, there exists a small enough number delta, such that if x is within that range, f(x) will be greater than M. Similarly, for lim x→∞ f(x) = L, it means that for any small number ε, there exists a large enough number X, such that if x is greater than X, f(x) will be within ε distance from L. These definitions do not involve using infinity or 0 as actual numbers

Then the game goes on forever. The point is that the person choosing the ##\delta## can never lose.
thats why its a limit becasue the game goes on forever.

FAQ: Understanding the Limit of 1/x as x Approaches Infinity and Zero

What is the limit of 1/x as x approaches infinity?

The limit of 1/x as x approaches infinity is 0. This means that as x gets larger and larger, the value of 1/x gets closer and closer to 0.

Why does the limit of 1/x approach 0 as x approaches infinity?

This is because as x gets larger and larger, the denominator of 1/x becomes infinitely large, causing the fraction to approach 0.

What happens to the limit of 1/x as x approaches 0?

As x approaches 0 from the positive side, the limit of 1/x approaches positive infinity. As x approaches 0 from the negative side, the limit approaches negative infinity.

How can we use the limit of 1/x to solve real-world problems?

The limit of 1/x can be used to solve problems involving rates of change, such as finding the velocity of an object at a specific point in time. It can also be used in economics and finance to calculate growth rates and interest rates.

Is the limit of 1/x always 0?

No, the limit of 1/x is not always 0. It depends on the value of x and the function it is being used in. For example, if x is approaching a finite number, the limit may be a different value. It is important to consider the context and the function being used when determining the limit of 1/x.
