WebJun 16, 2024 · The derivative of R ( t) is then given by R ˙ ( t) = ϕ ( t) R ( t). To derive the Lie algebra, later, it gives the 1st order expansion of R ( t) R ( t) ≈ R ( t 0) + R ˙ ( t 0) ( t − t 0) = I + t ϕ ( t 0), where t 0 = 0 and R ( t 0) = I . By given an assumption that ϕ ( t 0) = ϕ 0 around t 0, it gets R ˙ ( t) = ϕ ( t 0) R ( t) = ϕ 0 R ( t). WebA differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and its derivatives of various orders. A matrix differential equation contains more than one function stacked into vector form with a matrix relating the functions to their derivatives. polytheism meaning in bengali
