Compute: {{MATH_97}} {{CMD_98}} Let's graph this function to see what's going on: {{CMD_99}} {{ENV_100}} {{CMD_101}} Remark: Since {{MATH_102}} it follows that {{MATH_103}} This remark is very important, since the function {{MATH_104}} has two factors: {{CMD_105}} {{ENV_106}} {{CMD_107}} Hence we have that when {{MATH_108}} {{MATH_109}} and we see {{MATH_110}} and so by the Squeeze theorem, {{MATH_111}} In a similar fashion, when {{MATH_112}}, {{MATH_113}} and so {{MATH_114}} and again by the Squeeze Theorem {{MATH_115}}. Hence we see that {{MATH_116}} {{CMD_117}} {{ENV_118}} {{CMD_119}} {{CMD_120}} {{CMD_121}}
