RTCNTC said:Given -5π/6, find the reference number.
Let r = reference number
I decided to graph -5π/6.
r = -π - (-5π/6)
r = -π + 5π/6
r = -π/6
Book's answer for r is π/6.

A reference number is a unique combination of letters and/or numbers that is assigned to a particular document or transaction. It is used to identify and track the document or transaction, and may also be used for record-keeping and reference purposes.
The location of the reference number will vary depending on the type of document or transaction. It is usually included on the document itself, such as at the top or bottom of the page. For online transactions, the reference number may be provided in a confirmation email or on the website after completing the transaction.
No, not all documents and transactions have reference numbers. Some may only have a date or a unique identifier, while others may have a reference number as well. It depends on the purpose and system used for tracking and identifying the document or transaction.
In most cases, a reference number is unique and cannot be reused for another document or transaction. This ensures that each document or transaction has its own distinct identifier for tracking and reference purposes. However, in some systems, reference numbers may be reused after a certain period of time.
A reference number is important because it helps to identify and track a specific document or transaction. It can also be used for record-keeping, referencing, and resolving any issues or discrepancies that may arise. Without a reference number, it would be difficult to keep track of multiple documents or transactions and their status.
