Thank you for your help, I compiled the latest maxima and have been
trying your command:
However I am still unable to get an X-ax and Y-Ax in the middle:
I have been trying the following input, however I cant get it right.
I got a function that I substitute with an other function creating a new
function that I want to plot. I think I really need a good document with
examples how to port math that you do with your hands and head to
something I can enter in maxima.
