English
For a 1-form ω and a path γ, the curve integral function along γ at time t is given by applying ω to the point γ extended at t and to the derivative of the extended path at t.
Русский
Для 1-формы ω и пути γ функция криволинейного интеграла в момент t задаётся как ω(γ^{extend}(t)) применённое к производной пути γ^{extend}(t).
