Talk:Steady change
 | This article has not yet been rated on Wikipedia's content assessment scale. |
While not original research, this article seems to the following relevant portion of WP:NOR:
- In some cases, where an article (1) makes descriptive claims the accuracy of which is easily verifiable by any reasonable adult without specialist knowledge', and (2) makes no analytic, synthetic, interpretive, or evaluative claims, a Wikipedia article may be based entirely on primary sources (examples would include apple pie or current events), but these are exceptions.
