WebI'm trying to write a Python program to use Tanh-sinh quadrature to compute the value of \begin{equation} \int_{-1}^1 \frac{dx}{\sqrt{1-x^2}} \end{equation} but although the program converges to a sensible value with no errors in every case, it's not converging to the correct value (which is $\pi$ for this particular integral) and I can't find the problem. Web2. The Tanh-Sinh Quadrature Algorithm In a previous paper [11], one of the present authors and two co-authors investigated several numerical integration schemes, suitable for high-precision usage, and exhibited results for computer runs with 400- and 1000-digit preci-sion.

Web2. The Basic Tanh-Sinh Quadrature Scheme The tanh-sinh quadrature scheme is based on the Euler-Maclaurin summation formula, which implies that for certain bell-shaped integrands, approximating the integral by a simple step-function summation is remarkably accurate. This principle is utilized in the tanh-sinh scheme by transforming the integral ...

It is possible to express explicitly the Taylor series at zero (or the Laurent series, if the function is not defined at zero) of the above functions. The sum of the sinh and cosh series is the infinite series expression of the exponential function. The following series are followed by a description of a subset of their domain of convergence, where the series is convergent and its sum equals the function.
