20130111 14:18:16 +0200  answered a question  How to output data to a file I actually want to output just the x and y axis data. The provided link does not appear to provide me with this function. 
20130111 11:52:02 +0200  asked a question  How to output data to a file Here is my code that graphs a function: How do I output this data to a file so I can compare it to data generated by another piece of software? 
20121127 11:16:52 +0200  asked a question  Updating SageMath I am using Windows 7 and when I update SageMath I usually delete the old version (and the disk) and then update to the new .ova version. How do I save my worksheets or move them over?

20120816 11:42:11 +0200  asked a question  Solid lines in plot and grid lines I have a plot which sweeps over a range shown below and the plots it on a log scale on the horizontal axis (I am using 5.2 so the log scale feature is present).
Here is the entire formulation. The range on the yaxis I would like to see labeled is from 5 to 25. I asked a question before using the formulation below but the scale did not was off due to the wrong operator being used so I did not ask that particular question at the time: 
20120816 11:29:12 +0200  marked best answer  Sage .ova file for 5.1 works, does not work for 5.2 in Oracle VM The sage5.2.ova is the full Sage5.2 install. The notebook in that version has a bug and passwordless login doesn't work (which is why you are probably staring at a black screen when you run it). The somewhat arcane instructions below should get you going. But since we want the virtual machine to be easy to use we are currently distributing the old version until that bug is fixed.

20120815 17:41:56 +0200  asked a question  Sage .ova file for 5.1 works, does not work for 5.2 in Oracle VM I just used 5.1 with Oracle VM and it works fine. The 5.2 ova file does not work. I got the 5.2 file from here: http://www.stp.dias.ie/~vbraun/Sage/s... I was unable to fine the 5.2 .ova from the main page and navigate to it. The above link was provided to me in the answers. Any help would be greatly appreciated. Am I using a beta version of 5.2? I need the log scale feature of 5.2.

20120815 15:44:52 +0200  marked best answer  Deriving Data and Plotting I'm not getting the vertical range that you are specifying, but here is what I've got. Note that the log plot only works in the latest release (5.2) of Sage. 
20120815 15:35:41 +0200  asked a question  Where Do I Get Sage 5.2? I need the log scale features in 5.2, but whenever I select the link for 5.2 virtualbox appliance it takes me to a page with the .ova file listed as 5.1. 
20120815 15:34:28 +0200  answered a question  Deriving Data and Plotting It's okay, I got it to work with the abs defined where I wanted it and had one minor change to the equation to get the correct range. Now I need to find out how to get Sage 5.2. 
20120815 15:18:15 +0200  answered a question  Deriving Data and Plotting Thanks for the answer. I actually needed to have the absolute value of N x M(freq) and that should give me the right range. What is the correct syntax? I have tried log(abs(N x M(freq)),10)) and that does not seem to work and I get an error. Also, is there a reason for the change from freq to frq? Thanks! 
20120814 16:15:56 +0200  asked a question  Deriving Data and Plotting In the following x means multiply. Let In the following j is the imaginary representation
Now let The base formula is abs(20 x log(N x M,10)) or the absolute value of 20 log(N x M) where the log base is base 10. Within the base formula is freq (the value of the frequency) which will be swept from 10^8 to 10^11 in steps of deltaF (.2 x 10^9) The vertical range is from 25 to 5 (linear scale) and the horizontal range is from 10^8 to 10^11 (log scale) The horizontal axis as stated is a Log scale as opposed to Linear. How do I set this up in Sage to plot per the above? Thanks. 
20120814 11:24:03 +0200  commented question  Visual Simplification well this did not show up right. The first dotted line should separate adc omP1 omP2 which is the numerator and omZ1 which is the denominator and the second dotted line should separate (I 2 Pi + omZ1) which is the numerator and then (I 2 Pi + omP1)(I 2 Pi + omP2) which is the denominator. 
20120814 11:21:03 +0200  asked a question  Visual Simplification I want to take: and have it shown as: The * between, for example, I and 2 or 2 and Pi can be present, but I would like to see the equation in a more simplified form like the second case. I would even like to enter it in this way or at least have a way to convert.
