What Is Infinity Over Infinity - This is another common use of l'hôpital's rule. What you know about products of positive and negative numbers is still true here. See different approaches and examples from calculus, hyperreals, and indeterminate forms. (a)(∞) = ∞ if a > 0 (a)(∞) = −∞ if a < 0 (∞)(∞) = ∞ (−∞)(−∞) = ∞ (−∞)(∞) = −∞ ( a) ( ∞) = ∞ if a > 0 ( a) ( ∞) = − ∞ if a < 0 ( ∞) ( ∞) = ∞ ( − ∞) ( − ∞) = ∞ ( − ∞) ( ∞) = − ∞. Web in the case of multiplication we have. If you are finding a limit of a fraction, where the limits of both the numerator and the denominator are infinite, then l'hôpital's rule says that the limit of the fraction is the same as the limit of the fraction of the derivatives. Web learn why infinity divided by infinity is not a meaningful or defined operation in mathematics.
