Sep24 awarded Autobiographer Sep18 answered Is there an elementary proof for Euler's product for Sine? Sep15 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! Sep15 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!
