Sinc integrals and tiny numbers

  title={Sinc integrals and tiny numbers},
  author={Uwe Basel and Robert Baillie},
  journal={Elemente Der Mathematik},
We apply a result of David and Jon Borwein to evaluate a sequence of highly-oscillatory integrals whose integrands are the products of a rapidly growing number of sinc functions. The value of each integral is given in the form $\pi(1-t)/2$, where the numbers $t$ quickly become very tiny. Using the Euler-Maclaurin summation formula, we calculate these numbers to high precision. For example, the integrand of the tenth integral in the sequence is the product of 68100152 sinc functions. The…

Algorithmic Determination of a Large Integer in the Two-Term Machin-like Formula for π
In our earlier publication we have shown how to compute by iteration a rational number u2,k in the two-term Machin-like formula for π of the kind π4=2k−1arctan1u1,k+arctan1u2,k,k∈Z,k≥1, where u1,k
Unconditional Applicability of Lehmer’s Measure to the Two-Term Machin-like Formula for π
Lehmer in his publication [6] defined a measure $$ \mu=\sum\limits_{j=1}^J\frac{1}{\log_{10}\left(\left|\beta_j\right|\right)}, $$ where $\beta_j$ is a set of the constants that may be either


Some Remarkable Properties of Sinc and Related Integrals
AbstractUsing Fourier transform techniques, we establish inequalities for integrals of the form $$\smallint _0^x \prod\limits_{k = 0}^n {\frac{{\sin (akx)_{} }}{{akx}}dx.} $$ We then give quite
A remark concerning sinc integrals
We give a simple proof of Hanspeter Schmid's result that $K_n:=2\int_0^\infty\cos t\,\prod_{k=0}^n\mathrm{sinc}\left(\frac{t}{2k+1}\right)\mathrm{d}t=\pi/2$ if $n\in\{0,1,\ldots,55\}$, and

A Remark on Stirling’s Formula
We shall prove Stirling’s formula by showing that for n=1, 2,… $$n! = \sqrt {2\pi } {n^{n + 1/2}}{e^{ - n}} \cdot {e^{{r_n}}}$$ (1) where rn satisfies the double inequality
Surprising Sinc Sums and Integrals
We show that a variety of trigonometric sums have unexpected closed forms by relating them to cognate integrals.
