WebFrullani published the same formula and mentioned that he had communicated it to Plana (Italian astronomer and mathematician, 1781–1864) in 1821. To reproduce the Cauchy’s … In mathematics, Frullani integrals are a specific type of improper integral named after the Italian mathematician Giuliano Frullani. The integrals are of the form $${\displaystyle \int _{0}^{\infty }{\frac {f(ax)-f(bx)}{x}}\,{\rm {d}}x}$$where $${\displaystyle f}$$ is a function defined for all … See more A simple proof of the formula can be arrived at by using the Fundamental theorem of calculus to express the integrand as an integral of $${\displaystyle f'(xt)={\frac {\partial }{\partial t}}\left({\frac {f(xt)}{x}}\right)}$$ See more The formula can be used to derive an integral representation for the natural logarithm $${\displaystyle \ln(x)}$$ by letting $${\displaystyle f(x)=e^{-x}}$$ and $${\displaystyle a=1}$$: The formula can … See more WebApr 18, 2024 · People also read lists articles that other readers of this article have read..
