Groupprops:Voice

Articles dealing with mathematical constructs and not with real-world entities
For these articles the following guidelines are observed regarding voice:


 * When the subject is a mathematical construct, then we typically use the active voice. The situations where we use passive voice are ones where we want to emphasize the verb or the object.
 * When the subject is a generic human being and the object is a mathematical construct, we prefer to use passive voice to avoid referring to the subject at all. If active voice is used, typically a first-person plural is plural is chosen for the subject.

Articles dealing with real-world entities
Here the voice is chosen in accordance with the usual narrative style of historical documentation.
