Summary
| Description |
English: This diagram for the Wikiversity:Special relativity and steps towards general relativity course shows the relation between speed and rapidity. Use the octave source code below to produce a better quality postscript figure than the .svg figure. |

octave source code
The .svg version of the file, along with a better quality encapsulated postscript file, is produced by
- the following octave source code,
- in a local directory called /tmp
## octave script
## * output files created in /tmp : tanh.(eps|svg)
## * the .svg file is likely to have font problems, the .eps file should be OK
set(gcf(),"defaultlinelinewidth",3);
phi=linspace(-5,5,500);
plot(phi,tanh(phi),'-',
[-5 5],[-1 -1],'-k','linewidth',1,
[-5 5],[1 1],'-k','linewidth',1)
set(gca(),"fontsize",24, "linewidth",3);
xlabel('{\fontsize{32}\phi}');
ylabel('{\fontsize{32}\beta = tanh \phi }');
axis([-5 5 -1.5 1.5])
