redefine v(t) = If(0 ≤ t < 5.02, v1(t), 5.02 ≤ t, v2(t))

if variable of function is not x you must write (t) in commands

Just discover that after writing (t) in commands and saving file and reopening the file the argument (t) disappeared. wonder this is a bug. Thanks

I think it's a bug. Also redefining correctly the function the variable disappear after saving and reopening.

Same happens if using x instead of t.

This is why yesterday I addressed this to the developers.
