How it's used
Mathematical terms like this are often borrowed directly from English in casual classroom settings, so students frequently use the word sine instead of the formal Chinese term. Using the Chinese term is mostly restricted to formal textbooks or when explaining the concept in a structured academic environment. It is rarely heard in everyday social conversation outside of school or engineering contexts.
