设g(t) 在区间: [a,b] 内可积,则有: \lim_{n\to\infty}\int_{a}^{b} {\rm{d}} t g(t) \sin(nt) = 0 设: g(t) = \frac{f(t)}{\pi t} 就有: \lim_{n\to\infty}\lim_{\varepsilon\to 0}\int_{\mathbb{R}\backslash{[-\varepsilon,\varepsilon]}}{\rm{d}}t\,...
If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...

sarakkeet tulee jättää pois regressiomallista. Tätä ilmiötä kutsutaan "kolineaarisuudeksi", koska minkä tahansa redundantin x-sarakkeen voi ilmaista muiden, vaikuttavien sarakkeiden monikertojen summana.LINREGR-funktio tarkistaa kolineaarisuuden ja poistaa mahdolliset ...
This nationally representative data from Britain shows that distressing sexual function problems are not uncommon in young people (aged 16–21 years). In sex education and sexual health services, professionals need to acknowledge the importance of sexual well-being and provide opportunities for young ...
..,Pn∈H. Also ϒ∈H, and r is the radius with ‖μ1/2−ϒ‖>Φr and γ>0. A derivative is considered to be derived in the direction of ϒ−μ1/2 for f˙(An), such that (5.15)∂f(μ1/2,n,ϒ−μ1/2,n)=limt→0f(μ1/2,n+t(ϒ−μ1/2,n))...
Quantification of Gcg+ cells in ileal sections (n,o), n = 3 CD and HFHSD mice. Data are shown as mean ± s.e.m. of biologically independent samples. Statistical significance was determined by two-tailed Student’s t-test. Source data Full size image Next, we examined EEC ...
给定映射\(f:{R^n} \to R\) 并且\(dom(f) \subseteq {R^n}\)为凸集,那么\(f(tx + (1 - t)y) \le tf(x) + (1 - t)f(y)\)对于任意\(0 \le t \le 1\),且任意\(x,y \in dom(f)\)。如下图: 从图中可以看出,f的函数值总是位于连接f(x)和f(y)之间的直线下方。
