Another sine limit that also can be solved using Squeeze Theorem is: lim x→0 sinx x = 1 (4) 1.3 One-Sided Limits Simply put, one-sided limits are limits but only approaching from one direction. Left-Hand Limits: lim x→a− f(x) denotes the limit as x approaches a from the left, or as x increases to meet a. Right-Hand Limits: lim

### Calculus Limits - Online Community College

Left and Right Sided Limits: It is possible to determine the limit of a function that has an undefined answer by determining the left and right side of that limit. The left sided limit is denoted with a minus sign in the exponent, for example 3−, because the limit is being approached from the negative side.

7) Yes or No: If the one-sided limit lim x→a+ f(x) exists, then must the two-sided limit lim x→a f(x) exist? If your answer is Yes, then explain why. If your answer is No, then give a counterexample. A counterexample is a situation where the hypothesis (assumption) holds true, but the conclusion does not hold true.

### One-sided Limits and Continuity

Finding one-sided limits are important since they will be used in determining if the two-sided limit exists. For the two-sided limit to exist both one-sided limits must exist and be equal to the same value. lim xa. f x → exists if lim. f (x) − = L. and lim. f (xM) + = and L = M.
