I don't know if this should actually be asked on the English stackexchange. It seemed like I would find better answers here.
I have all but finished an undergraduate degree in mathematics in the United States, but I have never once heard the term "primitive" to mean "antiderivative" until recently, when someone from Europe pointed it out to me. According to him, it's a common term there. So I was wondering if people could give me an idea of how common this term is, and where. I know for sure that if someone says "primitive" to a math student in the US, that the student won't know what he is talking about. Does the reverse hold for "antiderivative" (or the also common "integral") elsewhere?
