8-24.

Evaluate the following limits. (Note the negative sign in parts (a), (b), and (c).)

The dominant term is in the denominator.

As, the fraction gets closer to.

The dominant term is

in the numerator (square root of is) and in the denominator, so the answer is the ratio of the coefficients.

The cosine function oscillates between

and forever. Since a limit must approach a single height, the limit does not exist.

Is the graph approaching the SAME height from both sides?

What height is the graph approaching as

?
