Theorem 2: If g'(x) exists and is continuous on [a,b] then \int_a^bf(x)\mathrm dg(x)=\int_a^bf(x)g'(x)\mathrm dx\tag3 Proof. Since g(x) is differentiable, we can use mean value theorem to guarantee the existence of \xi_k\in[x_{k-1},x_k] such that g(x_k)-g...

integration, in mathematics, technique of finding a function g(x) the derivative of which, Dg(x), is equal to a given function f(x). This is indicated by the integral sign “∫,” as in ∫f(x), usually called the indefinite integral of the function. The symbol dx represents an ...

(Fig.1band Supplementary Fig.1a). We observed that most (63%) LSRs in this clade contain DUF4368, a Pfam domain of unknown function, which is rarely (0.73%) found in site-specific LSRs (Supplementary Fig.1a), and that the clade includes LSRs in the TndX-like transposase subfamily29...
