Double-Exponential Quadrature Calculator

Let $f (x)$ be a function of real numbers in the interval $(a, b)$ , where $a$ and/or $b$ can be singular points (the points where $f (x)$ or $f^{'} (x)$ do not exist or are not finite), this application use double-exponential quadrature method to calculate the numerical integration $I$ : $I = \int_{a}^{b} f (x) d x$

For example, $f (x) = \sqrt{1 - x^{2}}$ , $a = 0$ , and $b = 1$ which is the singular point. But the quadrature can be calculated with this application.
