Substituting <em>x</em> with <em>π</em>/2 - <em>x</em> gives the equivalent integral,
So if we let <em>J</em> denote the value of the integral, we have
Condensing the logarithms, we have
log(tan(<em>x</em>)) + log(cot(<em>x</em>)) = log(tan(<em>x</em>) cot(<em>x</em>)) = log(1) = 0
since cot(<em>x</em>) = 1/tan(<em>x</em>), which means
and so the original integral has a value of <em>J</em> = 0.
Answer:
Which two details from the short story excerpt BEST support the correct answer above? A) "As if that could have anything to do with --with--My, wouldn't they laugh?" (section 1) "But you know juries when it comes to women. If B) there was some definite thing--something to show." (section 2) "No, Mrs. Peters doesn't need supervising. For that matter, a sheriff's wife is married to the law." (section 3) D) Then Martha Hale's eyes pointed the way to the basket in which was hidden the thing that would make certain the conviction of the other woman-- (section 4) Martha Hale snatched the box from the sheriff's wife, and got it in the pocket of her big coat just as the sheriff and the county attorney came back into the kitchen (section 5) E)
perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
-7 is 7 and - 9 would be 9
