Plotting in maple
I haven't used maple for a while and this could be a totally crazy question to ask. I was wondering if it is possible to plot a function of a function?

I have a function where the only variable in it is a function itself however I don't have an expression for this inner function but I do have restrictions.

e.g if I had something like
$x=a$+ $b+c$

where a and b are constants and c is a function of t. Is it possible to produce a graph of x verses t?

Code:

```First define your function of x f:=x->x^2-x sin(x); Now define x as a function of t. x:=2-3t; plot(f(x),t=-2*Pi..2*Pi)```
If this is not what you want please clarify.

Re: Plotting in maple
That is sort of what I was asking.

My problem is I don't actually have an expression for x. I know it's in terms of t but I don't have a form for it.

Is it still possible to plot this? My guess is not but I just want to check.

What type of relationship do you have between x and t?

If your first post you said that

$x=a+b+c(t)$

are you saying that you don't have an expression for $c(t)$?

If you only have an implicit relationship that is fine.

No I don't have an expression for c(t).

I guess that means I can't plot the graph.
