Bounty Points The person who is asked is or is selected by voting, and the person who is selected by voting will receive 20 points set by the system automatically as set by the questioner.

Reduced penalties Handling overdue questions 10 Questioners who are selected for overdue automatic voting questions or who ask questions deal with overdue questions, including and select no satisfactory answers, can get 10 points returned by the system.

Other actions Vote 1 can earn up to 20 points per day.

Reward Received a lot of praise 50 times 200 times, if the number of times it was rated "good" reached 80% of the total times, the system added 50 bonus points to the best person.

Just read what you know there, you 1 was selected, the other answered 71, each 2 points here is about 140 points, that 20, you have more than 110 points, some can only be answered more in a day, can only be counted as 20 points a day, so your points are not added wrong or not added.

The maximum score for long points by brushing is 20

It's best to answer well.

It can be used to **.

There is a limit to 2 points a day.

It seems like you can score 20 points in a day.

Definite integrals. The upper limit is positive infinity, the lower limit is 0, and the integral variable x is used as a commutation method.

When the variable variable is (x-1 x). The lower bound is originally 0, and when x tends to 0, (x-1 x) = negative infinity. So after the yuan exchange, the lower bound is negative infinity.

The upper bound of the definite integral is positive infinity, and when x tends to positive infinity, (x-1 x)=1 , so after the change of yuan, the upper bound is 1.

The interval of the definite integral (negative infinity, 1).

That is true.

Because the integrand is an odd function, it must be an even function after integration, and the even function has f(x)=f(-x), and if the upper and lower limits of the integral are a and -a, respectively, then there must be: f(a)-f(-a)=f(a)-f(a)=0

Okay, wait a minute.

It's OK to use the partial integration method.

Do you have any other questions, dear [hee-hee].

The question is gone, thank you, teacher.
