Document Summary
More practice problems are in the textbook as well as on the practice midterm. In each of the following cases, determine whether the limit exists as a nite number, and say its value if it is de ned. If the limit does not exist as a nite number, determine whether the limit is positive or negative in nity. If the limit does not exist as a nite number or as positive/negative in nity, explain why. lim x 0 (a) (b) (c) (d) (e) (f ) (g) (i) (j) f (x), where f (x) =! X, x 0 x > 0 x + sin(x) lim x x.
