(Section 2.1: An Introduction to Limits) 2.1.18 PART D: MORE EXAMPLES OF LIMITS THAT DO NOT EXIST (DNE)Example 12Let fx()=sin1x±²³´µ¶. Evaluate limx±0², limx±0+, and limx±0. (Figure 2.1.j) As xapproaches 0 from the left or from the right, the function values oscillate between ±1and 1. They do not approach a single real constant as xapproaches 0 from the left, nor from the right. Therefore, limx±0²does not exist (DNE),
