How to specify variables in a plot. Say I want something like,
At=S*x
S=4
plot(At,0,2)
Question is that how to instruct Sage that I want to plot against 'x'.
In Mathematica this is conveniently done by
Plot[At,{x,0,2}]

Thanks for your answer, it seems complicated :). I think it would have
been much easier if there is a way to specify the plot variables in
plots.

let us do,
f=function('f',x)
expr=f(x)
expr.operands()
the out put is,
[x]
Is it a bug?, I expect [f(x)].
using,
f=function('f',x)
expr=2*f(x)
expr.operands()
correctly gives,
[f(x),2]

and

gives false, assuming f is not a derivative itself.

I mean...
I do not know. If it is already evaluated to cos(x) then it should be
false (not *true*). current sympy gives false, I think I would go
with it.

No, it's not a bug since the operator
/___code___.py, line 11, in module
T.ode_solve(t_span=[_sage_const_0 ,_sage_const_1 ],num_points=_sage_const_100 )
