Under Etymology 1; I find it somewhat unlikely that cosine is using this root as the concept of cosine is not consistent with other examples of usage. The co- in cosine is similar to cooperative or coprocessor, meaning there are two entities involved, not that the cosine is a thorough version of sine. MagmaiKH (talk) 17:25, 7 September 2017 (UTC)
