Sep 24 awarded Autobiographer Sep 18 answered Elementary Proof of Euler's Sine Expansion $\prod_{k=1}^\infty\left({1-\frac{x^2}{k^2\pi^2}}\right)$ Sep 15 comment Integral $\int_{0}^1\frac{\ln\frac{3+x}{3-x}}{\sqrt{x(1-x)}}dx$ Many thanks! Differentiation of the integrand is a cool thing! Sep 15 comment Integral $\int_{0}^1\frac{\ln\frac{3+x}{3-x}}{\sqrt{x(1-x)}}dx$ Thank you! The product formula is especially nice!
