Let {{MATH_213}}. Consider {{MATH_214}}. Find a value {{MATH_215}} guaranteed by the Mean Value Theorem.
{{CMD_216}}
We first need to evaluate {{MATH_217}}.
{{MATH_218}}
Thus we seek a value {{MATH_219}} in {{MATH_220}} such that {{MATH_221}}.
{{MATH_222}}
There is another such point: {{MATH_223}}.
Indeed,
{{MATH_224}}
A graph of {{MATH_225}}, along with a rectangle with height
{{MATH_226}}, is pictured below. The area of the rectangle is the
same as the area under {{MATH_227}} on {{MATH_228}}. The two points {{MATH_229}} and {{MATH_230}} are also shown in the figure.
Recall, {{MATH_231}}.
