Set {{MATH_88}} and {{MATH_89}}. Since {{MATH_90}} and {{MATH_91}} this is a limit with form {{MATH_92}}, so L'H{{CMD_93}}pital's Rule (LHR) applies. This gives: {{MATH_94}} This right-hand side is another limit with form {{MATH_95}}, so we can use LHR again. {{MATH_96}} This limit has numerator tending to {{MATH_97}} and denominator tending to {{MATH_98}}, making this limit have value {{MATH_99}}. {{MATH_100}} {{CMD_101}} {{CMD_102}}
