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).
In mathematics, matrix calculus is a specialized notation for doing multivariable calculus, especially over spaces of matrices. It collects the various partial derivatives of a single function with respect to many variables, and/or of a multivariate function with respect to a single variable, into vectors and matrices that … See more Matrix calculus refers to a number of different notations that use matrices and vectors to collect the derivative of each component of the dependent variable with respect to each component of the independent … See more There are two types of derivatives with matrices that can be organized into a matrix of the same size. These are the derivative of a matrix by a scalar and the derivative of a scalar by a matrix.
