Improper Integrals on 42 platforms

\(\int_{-\frac{\pi}{4}}^{\frac{\pi}{3}}\frac{\left |\sin x \right |}{x}dx=\int_{-\frac{\pi}{4}}^{0}\frac{\left |\sin x \right |}{x}dx+\int_{0}^{\frac{\pi}{3}}\frac{\left |\sin x \right |}{x}dx\)

Or, remove the discontinuity: integ(sin(x)/x, x, pi/4, pi/3) ~ 0.226483
