L'Hopital's Rule - Calculus

This calculus video cover a tutorial on how to prove L'Hopital's rule for indeterminate limits. L'Hospital's rule is used to evaluate limits of the indeterminate forms 0/0 and infty/infty. An informal proof of L'hopital's rule is given for limits of the indeterminate form infty/infty. The basic idea of L'hopital's rule is to take the derivatives of the functions in the numerator and denominator until the limit becomes determinate.
