Hi!
I get the following with sage-8.4.beta5:
sage: f(x) = cos(pi*x)
sage: (f(x)*exp(-I*pi*x)).integral(x)(x=1/2) -
(f(x)*exp(-I*pi*x)).integral(x)(x=-1/2)
1/2
sage: (f(x)*exp(-I*pi*x)).integral(x,-1/2,1/2)
1
The previous two expressions are not equal, but I think they should be
equal.
I do the following:
- cd ~/bin
- untar the Ubuntu 16.04 version
- rename the ~/bin/SageMath to ~/bin/SageMath-8.3 so that I can have
multiple versions if needed.
- ln -s ~/bin/SageMath-8.3/sage sage-8.3
- ln -s ~/bin/SageMath-8.3/sage sage # My default version
~/bin is in my path, so I can j
So it seems that when I make a symbolic link to /usr/share, running sage
crashes
But when I run it directly from the install directory using : ./sage,
everything runs fine, patches are compiled, and I get through to running a
notebook.

Hi,
I went through other posts with the same title, and tried several different
ways to install sage, all without success :
1) with apt : apt-get install sage-jupyter
2) downloading the latest Ubuntu 16 binary : since there are no Ubuntu 18
binary I chose the most recent one, then ran sage.

Dear friends - I have a quotient which I need to differentiate and show the
differential is always positive for unknown H>0. We have 7 unknown
constants all known to be positive and less than 1 except for A which may
be any positive value. In Sage Cell Server I did this
var('A','K1','K2','K3','

"Uglier" only internally. I think it shouldn'
