begin{align*} &f(x) = dfrac{1}{1+x^2}end{align*}

Integrating with respect to x from 0 to 1 yields 0.25π. What makes this a guided approach is that this integration range can be […] • begin{align*}& {rm{Given}}:int_0^infty f(x) dx & &(1) : rm{Queen : Property} & &therefore u=(x)^{-1} Longrightarrowint_0^infty f[(x)^{-1}] (x)^{-2} dx & &(2) : rm{Jacksonian : Property} […]
