 18 Integrating $\int_0^\infty\frac{\log (1+z^2)}{e^z-1}dz$ using residue calculus. 12 Can a substitution cause a convergent definite integral to diverge? 11 proof that $e^x$ is a transcendental function of $x$? 11 Integration method for $\int_0^\infty\frac{x}{(e^x-1)(x^2+(2\pi)^2)^2}dx=\frac{1}{96} - \frac{3}{32\pi^2}.$ 8 Is it possible to express $e$ in terms of $\pi$ algebraically and vice-versa?
