Description

Sine and cosine are not implemented, as you state in the [paper](https://arxiv.org/abs/2212.11429):

> For example, we do not currently have a way to compute sharp Taylor enclosures for periodic functions, such as sine or cosine.

I only skimmed the paper, but I assume periodic functions are a non-trivial limitation?
