Functions of several real variables
WebA real-valued is a function f:D →R, where D ⊆ R2 usually (but not always!) viewed as geometrically as lying in the “ xy-plane” Each (x, y) ∈ D is assigned a unique real number z= f(x, y) ∈ R. D is the domain of f and the set of all such corresponding z is called the range. We refer to x and yas independent variables and z as the dependent variable. WebJan 10, 2024 · Quite thorough investigations were carried out on questions concerning the connection between the smoothness properties of a function of several variables and the rate of decrease of its best approximation by algebraic and trigonometric polynomials, as well as by entire functions.
