variables to 'real'.
1) Here is a full short example:
var('h','t','px','py','pz','w','R')
P=vector([px,py,pz])

Greetings,

the solution is either known or obvious to someone on this forum, but I
would appreciate any constructive input.
When I try to make a graph with the following:
p1=plot(delta.substitute(px=5,py=0,pz=1,R=1,h=10,w=
