We can extend to vector-valued functions the properties of the derivative. In particular, the constant multiple rule, the sum and difference rules, the product rule, and the chain rule all extend to vector-valued functions. However, in the case of the product rule, there are actually three ...
This work depends on the paper Extensions of vector-valued Baire one functions with preservation of points of continuity (Koc and Kolá (2016) [20] ).doi:10.1016/j.jmaa.2016.11.080Koc, MartinKolá?, JanJournal of Mathematical Analysis & Applications...
Earlier, we saw that functions are differentiated by using the limit of the variable in the quotient. But vectors, as we know, are not like scalars in that we cannot divide by vectors, which creates the need for new definitions for vector-valued functions. We can define a vector function ...
Based on the implicitly restarted Arnoldi method for eigenpairs of large matrix, a new method is presented for the computation of a few eigenpairs and their derivatives of large matrix-valued functions. Eigenpairs and their derivatives are calculated simultaneously. Equation systems that are solved for...
denote the complex version of W, W a , respectively. 7 For each symbol a, define the vector-valued function f a on W by f a (w) = w∆ a /r a (w), where r a (w) = w∆ a 1. For any fixed n and z 0 −n , define x i = x i (z i −n ) = p(...

For instance, the vector field of directors of polar liquid crystals is instantaneous, also known as space-like vector field. Instantaneous spacetime tensor fields are characterized numerically by vanishing contravariant coordinate functions, which are related to the time base vector. Apparently a ...
As we saw earlier, in single variable differentiation, we can take second derivatives of functions (within reason, of course), but in multivariable calculus, we can also take mixed partial derivatives, as illustrated here: You may have noticed that when we take a mixed partial derivative, the...
