As reported,
var('r')
assume(r>0)
integrate(r * sqrt( (2*r*cos(x)/sqrt(3))^2 + ( 2/3 + 4*r*sin(x)/3 )^2 ), x)
gives
-1/12*(2*r*x - r*sin(2*x))*r
which is indeed incorrect. Is the root cause known?

Dear Mr Andrey Novoseltsev,
I am writing you to repor
I want to test finding the discrete log in the circle group over Z/Zm --
discrete logs of g^a mod m, where g is a complex number and m is composite.
Can Sage do this for large composite m, say on the order of 2^128 or more,
when m is smooth, containing no prime factors larger than say 1 billion
I am a student and I definitely agree with Chris Seberino here. I don't
think it is the job of software (or, rather, it is not good CAS design) to
try and teach people mathematics in this way. I think that the CAS should
be as convenient and intuitive as possible. As an example, I didn't even
k
