Equivaiently, we may say that there exists a sequence (. : n = 1,2,…) of polynomials such that ||.–.|| → 0 as . → ∞. Is it possible to denote explicitly a sequence (.) satisfying this condition? The answer is affirmative. For . = we may choose for . the . .(.), defined on by

For any . ∈ .(ℝ,.) there is an analogous notion, although now it is not a sequence of numbers but again a function defined on the whole of ℝ. Precisely formulated, for . ∈ .(ℝ,.) the . . of . is the function, defined for any . ∈ ℝ by

Fourier Series of Continuous Functions, (f.) is said to be an . on .. We immediately mention an example. For . = 0, ±1, ±2,…, let .(.) = (2π). on ℝ. The system (. : . = 0, ±1, ±2,…) is orthonormal on any interval [., . + 2π], i.e., on any interval of length 2π in ℝ. The proof is immediate by observing that
