# Can you use L Hopital for infinity over infinity?

## Can you use L Hopital for infinity over infinity?

Note that both x and e^x approach infinity as x approaches infinity, so we can use l’Hôpital’s Rule. Note that for the last fraction, the limit of the numerator and denominator are both zero, which is another case where we can apply l’Hôpital’s Rule. …

## What is the limit of infinity over zero?

A number over zero or infinity over zero, the answer is infinity. A number over infinity, the answer is zero.

Is 0 to the power of infinity indeterminate?

Answer: Infinity to the power of zero is equal to one. Let’s understand the solution in detail. Explanation: ∞0 is an indeterminate form, that is, the value can’t be determined exactly. ⇒ limn→∞ n0 = limn→∞ 1 = 1.

### Can you set infinity to zero?

You must make it clear what infinity you are talking about in order to work with it. In summary, the expression ∞×0 using multiplication defined for the natural numbers does not have any meaning, so it cannot be said to be equal to 0.

### What is the value of zero into infinity?

Any number multiplied by 0 is 0. Any number multiply by infinity is infinity or indeterminate. 0 multiplied by infinity is the question. Answer with proof required.

What is L’Hopital’s rule for zero over zero?

THEOREM 1 (l’Hopital’s Rule for zero over zero): Suppose that lim x → af(x) = 0 , lim x → ag(x) = 0 , and that functions f and g are differentiable on an open interval I containing a. Assume also that g ′ (x) ≠ 0 in I if x ≠ a. Then lim x → a f(x) g(x) = lim x → a f ′ (x) g ′ (x) so long as the limit is finite, + ∞, or − ∞.

## Which is L’Hopital’s rule for Infinity over infinity?

THEOREM 2 (l’Hopital’s Rule for infinity over infinity): Assume that functions f and g are differentiable for all x larger than some fixed number. If lim x → af(x) = ∞ and lim x → ag(x) = ∞ , then lim x → af(x) g(x) = lim x → af ′ (x) g ′ (x) so long as the limit is finite, + ∞, or − ∞.

## How to apply L Hopital’s rule in calculus?

Occasionally, a limit can be re-written in order to apply L’Hôpital’s Rule: lim x → 0 xlnx = lim x → 0 lnx 1 x = lim x → 0 1 x − 1 x2 = lim x → 0 ( − x) = 0. We can use other tricks to apply L’Hôpital’s Rule.

How many times can you use L Hopital’s rule?

Sometimes it is necessary to use L’Hôpital’s Rule several times in the same problem: lim x → 0 1 − cosx x2 = lim x → 0 sinx 2x = lim x → 0 cosx 2 = 1 2. Occasionally, a limit can be re-written in order to apply L’Hôpital’s Rule: lim x → 0 xlnx = lim x → 0 lnx 1 x = lim x → 0 1 x − 1 x2 = lim x → 0 ( − x) = 0.
