Answer 2

$\huge{\boxed{\mathbb\pink{♡}{\mathbb{ANSWER}}\pink{♡}}}$

The upper limit is less than the lower limit. This is opposite of the usual situation, so simply switch the limits and put a minus sign in front. Then the new definite integral will be positive for the obvious reasons and combined with the new minus sign, this yields a negative result for the whole thing.
