Find the extreme values of {{MATH_215}} on the interval {{MATH_216}}. {{CMD_217}} The derivative is {{MATH_218}} {{ENV_219}} The critical points are {{MATH_220}} and {{MATH_221}} (both these lie in {{MATH_222}}), with values {{MATH_223}} and {{MATH_224}}. The endpoints have values {{MATH_225}} and {{MATH_226}}. That gives us a list of values {{MATH_227}}. The global maximum value of {{MATH_228}} is {{MATH_229}} (occurring at {{MATH_230}}) and a global minimum value of {{MATH_231}} (occurring at {{MATH_232}} and {{MATH_233}}). {{CMD_234}} {{CMD_235}}
