Is it possible to define a custom constant like pi? One that is handled symbolically, one that can be used without prior definition...

For example, could it be possible to define "tau" to equal 2*pi for my Sage installation so that when I open my notebook, I can call "tau" without needing to define it in every cell?

And to take it a step further, would it be possible to replace constants? Like pi with tau/2? This isn't as important, but it would be very nice!

Just define the variables, functions, or other things in a file, and load it into Sage at startup. There are a number of questions and answers along these lines already on this site:
