In fact, if $\sin(x)$ did have a fixed value of 0.75, our integral would be: $\int \text{fixedsin}(x) \ dx = \int 0.75 \ dx = 0.75 \int dx = 0.75x$ But the real $\sin(x)$, that rascal, changes as we go. Let's see what fraction of our path we really get. ...
摘要: 对积分Ι=integral from n=0 to +∞((sinx/x)dx)=π/2的计算方法进行深入研究,从多种渠道得出这一结果,值得注意的是本文应用了Fourier积分变换的对偶性质,巧妙而不失优美地给出了一个新方法,同时还得到一个新的收敛积分:integral from n=0 to +∞((sinx/x)~2dx)=π/2.关键词:...
