Limit of an exponent when it goes to infinity

In summary, when an exponent goes to infinity, the limit is equal to infinity. To calculate this limit, use the rule that states the limit of x^n as x goes to infinity is infinity if n is positive, and 0 if n is negative. When the base of an exponent is greater than 1, the limit will also be infinity, and when the base is between 0 and 1, the limit will be 0. The limit of an exponent cannot be negative when it goes to infinity because the exponent will always result in a positive value.

how this thing works ?

integration of e to the power of (-x) from 0 to infinity

sorry , not good in using the symbols ..^.^ ~

Hi
Do you know what the primitive of e^{-x} is ?

First integrate it, then you get [-e-x] from 0 to infinity.

The key is to find the limit as x approaches infinity of (-e-x).

(Hint: Put in a very large negative value for x and see what you get.)

Related to Limit of an exponent when it goes to infinity

What is the limit of an exponent when it goes to infinity?

When an exponent goes to infinity, the limit is equal to infinity. This means that the value of the exponent continues to increase without bound as the input value approaches infinity.

How do I calculate the limit of an exponent when it goes to infinity?

To calculate the limit of an exponent when it goes to infinity, you can use the rule that states the limit of xn as x goes to infinity is infinity if n is positive, and 0 if n is negative.

What happens to the limit of an exponent when the base is greater than 1?

When the base of an exponent is greater than 1, the limit of the exponent as it goes to infinity will also be infinity. This is because as the input value increases, the exponent will also increase, resulting in a larger and larger value.

What happens to the limit of an exponent when the base is between 0 and 1?

If the base of an exponent is between 0 and 1, the limit of the exponent as it goes to infinity will be 0. This is because as the input value increases, the exponent will decrease, resulting in a smaller and smaller value.

Can the limit of an exponent be negative when it goes to infinity?

No, the limit of an exponent cannot be negative when it goes to infinity. This is because as the input value increases, the exponent will always result in a positive value, regardless of the sign of the base.
