I tried to evaluate the infinite product: prod((2^n-1)/2^n) (n=1,oo) by converting the product to a sum via logarithm: sum(log(1-2^-k),k,1,oo) The sum (and thus the product) should, according to WolframAlpha, converge with a final value of about -1.24206 This video (https://www.youtube.com/w

I recently stumbled upon something that looks like a bug: Try to integrate the following function: f(x)=log(1-4*cos(x)+4) integrate(f,x,0,pi) According to the following video (https://www.youtube.com/watch?v=nscSDYApAjM) the result should be 2*pi*log(2) But my local Sage as well as online I g
