ABSTRACT
We offer an alternative method for evaluating Dirichlet’s integral, i.e., the integral of the sinc function 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 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。
