Here is the official definition of a double integral of a function of two variables over a rectangular region R R as well as the notation that we'll use for it. ∬ R f (x,y) dA= lim n, m→∞ n ∑ i=1 m ∑ j=1f (x∗ i,y∗ j) ΔA ∬ R f ( x, y) d A = lim n, m → ∞. ⁡. ∑ i = 1 n ∑ j = 1 m f ( x i ∗, y j ∗) Δ A. Note the. In mathematics, the double factorial or semifactorial of a number n, denoted by n‼, is the product of all the integers from 1 up to n that have the same parity (odd or even) as n. That is, !! = = ⌈ ⌉ = (). For even n, the double factorial is !! = = = (), and for odd n it is !! = = + = (). For example, 9‼ = 9 × 7 × 5 × 3 × 1 = 945.The zero double factorial 0‼ = 1 as an empty product Section 4-3 : Double Integrals over General Regions.
