In-place [`cos`](./cos.md#cos): writes the result through `self`; same formula, arguments, and error conditions as [`cos()`](./cos.md#cos). A view input writes through its base storage. Returns `self` under the value surface, [`Result`](../Result.md)`<void>` under the [`Result`](../Result.md) surface; [`CLIKART_CHECK`](../../index.md#CLIKART_CHECK) is the mode-stable spelling.
