If this limit exists, then we should be able to look sufficiently close, but not at, {{MATH_112}}, and see that {{MATH_113}} is approaching some number. Let's look at a graph: {{CMD_114}} {{ENV_115}} {{CMD_116}} If we look at what happens for {{MATH_117}} values getting closer and closer to {{MATH_118}}, but staying on the left-side of 2, we see that {{MATH_119}}. However, if we allow the values of {{MATH_120}} getting closer and closer to {{MATH_121}}, but staying on the right-side of 2, we see {{CMD_122}} {{ENV_123}} {{CMD_124}} That is, for values of {{MATH_125}} close to {{MATH_126}} but larger than {{MATH_127}}, {{MATH_128}}. We cannot find a single number that {{MATH_129}} approaches as {{MATH_130}} approaches 2, and so the limit does not exists. {{CMD_131}} {{CMD_132}}
