[sage-support] installation issues with sage 7.6

2017-03-30 Thread Alex Jordan
I'm installing Sage for the first time, on a Mac OS El Capitan. I downloaded from: http://files.sagemath.org/osx/intel/index.html the file sage-7.6-OSX_10.12.3-x86_64.app.dmg, and dragged Sage into Applications. The first time I opened Sage, a window opened that asked if I wanted to update som

Also, I realized that, more generally, conjugate passes through sin because of the holomorphicity: sage: conjugate(sin(1+I)) sin(-I + 1) Maybe this would be nice for other holomorphic functions, like zeta? But perhaps that's how you had in mind to implement it anyways. -- You received this mes
