Graphs not working with previously defined symbols
Graphs not working with previously defined symbols
(OP)
Specific problem:
I have a function w(s) = ...
When I try to graph the function using the variable 's', I get an error because the graph thinks s is a second and not a variable.
s:=s doesn't work as implied on other web pages.
How do I undefine s?
General problem:
The above doesn't seem to work for any previously defined symbol (x, t, L, etc).
Is it possible to graph using a previously defined symbol as it's variable?
Thanks!

RE: Graphs not working with previously defined symbols
However, if a variable is already defined, then you need to make it into a range variable or vector to get a plot.
If you are otherwise not using units, you could turn off the units altogether.

i:=0..100
s[i:= -50ft + i*2ft
w(s) now graphs, yay!
Although the above takes a some thought to set up right. I'm wondering if there is an easier way? It would be ideal if there were a way to undefine a unit.
I do need units, I don't want to disable them completely.
