#sage math

Thanks for all the help guys, and also the suggestions. END UPDATE

I need help installing sage-manifolds 0.5 onto Mac OS X Mavericks, with Sage 6.3 installed from binaries. Thanks

sagemanifolds 0.5 installation troubles (that I'm having) Mac OS X Mavericks setup Here's what I wrote to the authors of sagemanifolds, Bejger and Gourgoulhon; also if anyone is really interested, I can email you the Terminal Output I had, just leave a message on tumblr with your email: Hi Bejger and Gourgoulhon, Thank you for your quick replies! Yes, I have, in all cases, been typing in the directory where Sage is installed. I check the directory with ./sage -root and pwd The Terminal Outputs which I will include in this email are long and understandably I wouldn't expect anyone to read through it, but I'll copy and paste some snippets from them in this email. So for instance, I know where the sage math root is this way: -rw-r--r--@ 1 ernestyeung staff 3630 Sep 8 16:26 sm-install-macos-bsd.sh Chuns-MacBook-Pro:Downloads ernestyeung$ cd /Applications/Sage-6.3.app/Contents/Resources/sage Chuns-MacBook-Pro:sage ernestyeung$ pwd /Applications/Sage-6.3.app/Contents/Resources/sage Chuns-MacBook-Pro:sage ernestyeung$ ./sage -root /Applications/Sage-6.3.app/Contents/Resources/sage In Terminal Saved Output sm2, I try sudo ... as well: Chuns-MacBook-Pro:sage ernestyeung$ sudo bash sm-install-macos-bsd.sh But essentially I get the same errors during installation, as with simply using bash sm-install-macos-bsd.sh sdk / -find as 2> /dev/null as: error: unable to find utility "as", not a developer tool or in PATH error: command 'gcc' failed with exit status 1 Now in both of these cases, I do this on the install of Sage 6.3 where I just drag the icon into my Application folder (all done in root). Also, on 2 different Macs, but with Mavericks on both, I have XCode 5 installed, along with the command line tools, and Mac ports for gsed. I tried a sage install from source, but I'm having trouble there as well (Terminal Saved Output sage1). Thanks for your time, I don't have any trouble with sagemanifolds 0.4, so I'll use that in the mean time, although I appreciate that 0.5 is a major update with your tensor module. There aren't anything else I could think of to try, so I'm going to have to do other stuff. Thanks again, -Ernest Yeung.

Declare multiple variables in Sage Math I just do this: x1, x2 = var( ['x' + str(i) for i in range(1,3) ] ) or this x0, x1, x2, x3 = var(['x' + str(i) in i in range( 0 , 4) ] ) I tried searching on the internets for another way, but didn't find anything. This is useful for declaring components of a coordinate field, components of a coordinate vector, components of a vector, or a numbered list, range, of variables.

= UsD.chart(r'th:(0,pi]:\theta ph:[0,2*pi):\phi')

and you now have manifolds.
