In summary, the limit at infinity of an equation is the value or behavior of the equation as x becomes very large. It can be a specific value, positive or negative infinity, or 0. To determine the limit at infinity of a rational function, the degrees of the numerator and denominator are compared. The graph of an equation will approach a horizontal asymptote as x goes to infinity, and the location of the asymptote can be found by finding the limit at infinity. The limit at infinity of an equation can change if the equation is manipulated, so it is important to consider this when solving equations.

when x goes very large, say infinite, what does this equation will look like?

H is a constant

1) 1/(1+(x/H)^2)^(1/2))

2) 1/(1+(H/x)^2)^(1/2))

The answers are

1) 1/x^2

2) 1/x

But I am not too sure how to get there. Thank you

1) 1 + x/h^2 is x/h^2 as x gets larger. Now you have 1 / (x/h^2)^1/2 which is h/x.

Try x = 10000 H = 5. => 4.99E-4. 5/10000 = 5E-4

2) (H/x)^2 is 1/x^2 as x gets larger? Then 1 + 1/x^2 is 1 as x gets larger. Now you have 1 / 1^1/2 which is 1.

Try x = 1000 H = 5. => .999.
 

1. What is the limit of the equation if x goes to infinity?

The limit of an equation as x goes to infinity is called the limit at infinity. This means that we are looking at what happens to the equation as x becomes very large, or approaches infinity. The limit at infinity can be a specific value or it can be infinity or negative infinity.

2. How do you determine the limit at infinity of a rational function?

To determine the limit at infinity of a rational function, you need to look at the highest power of x in the numerator and denominator. If the degree of the numerator is greater than the degree of the denominator, the limit at infinity will be either positive or negative infinity. If the degrees are equal, then the limit at infinity will be the ratio of the leading coefficients. If the degree of the denominator is greater than the degree of the numerator, the limit at infinity will be 0.

3. Can the limit at infinity of an equation be a specific value?

Yes, the limit at infinity of an equation can be a specific value. This occurs when the highest power of x in the numerator and denominator are equal, and the limit can be found by taking the ratio of the leading coefficients. However, it is important to note that the limit at infinity can also be infinity or negative infinity, depending on the degrees of the numerator and denominator.

4. What happens to the graph of an equation as x goes to infinity?

As x goes to infinity, the graph of an equation will approach a horizontal asymptote. This means that the graph will get closer and closer to a specific value, but will never actually reach it. The location of the asymptote can be determined by finding the limit at infinity of the equation.

5. Can the limit at infinity of an equation change if the equation is manipulated?

Yes, the limit at infinity of an equation can change if the equation is manipulated. For example, if the equation is multiplied by a constant, the limit at infinity will also be multiplied by that constant. Similarly, if the equation is divided by a variable, the limit at infinity will be divided by that variable. Therefore, it is important to be cautious when manipulating equations and to consider the limit at infinity in order to maintain the accuracy of the result.
