ABSTRACT

We offer an alternative method for evaluating Dirichlet’s integral, i.e., the integral of the sinc function sin ( t ) / t over the positive real line. Our method employs the fundamental theorem of calculus for complex path integrals, but avoids the customary invocation of Cauchy’s theorem.

关于Dirichlet的Sinc积分的注释

摘要

我们提供了另一种方法来评估Dirichlet积分,即Sinc函数的积分 Ť / Ť 在正实线上。我们的方法对复杂的路径积分采用微积分的基本定理,但避免了柯西定理的惯用调用。
