Queuing Rule of Thumb

The Queuing Rule of Thumb (QROT) is a mathematical formula, known as the queuing constraint equation when it is used to find an approximation of servers required to service a queue. The formula is written as an inequality relating the number of servers (s), total number of service requestors (N), service time (r), and the maximum time to empty the queue (T): QROT serves as a rough heuristic to address queue problems. Compared to standard queuing formulas, it is simple enough to compute the necessary number of servers without involving probability or queueing theory. The rule of thumb is therefore more practical to use in many situations. (Wikipedia).

Limits are...weird...for multi-variable functions | Limits along paths

In single variable calculus, you only had to take a limit from the left and from the right. In multi variable calculus, you can approach from every single direction. One way to say a limit doesn't exist is then to find two different paths where along those two different paths the limit app
