L'Hopital's Rule
L'Hopital's rule is another way to solve limits, but with using derivatives. The idea is to first plug in the constant into the function. If the result is 0/0, then we can use L'Hoptal's. L'Hopital's Rule works by taking the derivative of the numerator and the denominator, and then plugging in the constant to find the limit. If the result is still 0/0, then we can apply L'Hopital's rule again to find the limit.
Now let's try an example problem.
