4-137.
  1. Without your calculator, evaluate the following limits. Homework Help ✎

Notice that this is a right-sided limit because x = 3 is an endpoint on

There is no limit from the left of the endpoint; so, consequently, this must be written as a one-sided limit.

This is a limit to infinity. We are looking for end-behavior. Compare the highest-power term in the numerator and the denominator.

There is a horizontal asymptote of y = 0.

This is Ana's Definition of the Derivative:

f(x) = cosx and a = π

So Ana's derivative can be evaluated as:

The limit is equal to f ' (π).
