Thread: 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
+

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

I think this is what your question is asking.

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.

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



are you saying that you don't have an expression for ?

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.
