Web22 May 2024 · Expressions involving vectors or matrices of a set of variables can be viewed as functions of those variables, e.g. c ′ x = c1x1 + c2x2 + ⋯ + cnxn = f(x1, x2, ⋯, xn). These can, of course, be partially differentiated. “Differentiation rules” can be developed that allow us to compute all the partial derivatives at once, taking ... WebD f ( a) = [ d f d x ( a)]. For a scalar-valued function of multiple variables, such as f ( x, y) or f ( x, y, z), we can think of the partial derivatives as the rates of increase of the function in the …
