Why is the integral an area?

Question

Python

Good day. Explain why the definite integral is the area of ​​a curved figure?

Answer 1

Get the user's ip, find out the location from it

Answer 2

In general, as I already commented above, there is a request everywhere
or
Here it is pretty well stated.
With one "but" - MongoDB .
I think if you dig into the reference books (and they are also in Russian), then you can rewrite this under the DB provided by the hoster.
Yes, in the end, you can drive it all in, say, CSV.
But the easiest way is to run something like this on the server side:

<?php
$file="stat.log";    // файл для записи истории посещения сайта
$col_zap=500;    // ограничиваем количество строк log-файла 

function getRealIpAddr() {
  if (!empty($_SERVER['HTTP_CLIENT_IP']))        // Определяем IP
  { $ip=$_SERVER['HTTP_CLIENT_IP']; }
  elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) 
  { $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; }
  else { $ip=$_SERVER['REMOTE_ADDR']; }
  return $ip;
}

if (strstr($_SERVER['HTTP_USER_AGENT'], 'YandexBot')) {$bot='YandexBot';} //Выявляем поисковых ботов
elseif (strstr($_SERVER['HTTP_USER_AGENT'], 'Googlebot')) {$bot='Googlebot';}
else { $bot=$_SERVER['HTTP_USER_AGENT']; }

$ip = getRealIpAddr();
$date = date("H:i:s d.m.Y");        // определяем дату и время события
$home = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];    // определяем страницу сайта
$lines = file($file);
while(count($lines) > $col_zap) array_shift($lines);
$lines[] = $date."|".$bot."|".$ip."|".$home."|\r\n";
file_put_contents($file, $lines);
?>

At the output, we get something like this: All that
remains is to parse the log file (there are a lot of modules for python)

Answer 3

By definition, friend.
By definition, the definite integral is the limit of the sum of the bar areas into which the space under the graph can be cut.
Are definitions hidden from you? This mess!
