This question is curve handled by a vector-valued function

@janhardo 

Don't know how to start with this asked vector-valued function for a Curve in this task
Could be too difficult for me ?

Note: some background information how to handle Curves

Thanks

The parametric description i can understand with calculus, but with vector-Calculus i should do need more experience.    

@Carl Love 

Thanks

I will look at it

@Carl Love 

Thanks

That awesome power of Maple is is then versatility to program on different ways ?
   

@Carl Love 
Thanks

Yes, too difficult, although it are 2 position vectors ( velocity, accelaration) moving along the Curve and that is rather easy to imagine.
The length of the folium is a lineintegral ?

@Carl Love 

Thanks

I got all sorts of lists , its about list-building with high level commands as i understand it.

@Carl Love 

Thanks

Maybe understandable for me in a easy example.?
The book examples are less demanding for advanced programming ? 

 @Carl Love 

Thanks

I see a example : folium of Descartes made by a vector function 

@acer 

Thanks

"Taking a list of numeric values L, and producing a list of lists [p,f(p)] for every p in L , is not complicated. In fact it is a quite straightforward and rather basic example of Maple programming".

This formulation makes it clear
Its a principle in teaching: from basic to complicated.    

@acer 

Thanks

Language interpretations are always a issue,that 's a disadvantage, but it is as it is.

Both axes to the very same extent as i can translate it.:

Then the x-axis and y axis are the same. (identical)

@acer 

Thanks

I made a summarize already from the ex set task3 last week :done on different ways 
So i can see what the difference is

These commands are complicated although knowing what they intended to do  

Q := map(p->[p,f(p)], L); #  x-values are evaluated in function f

T := seq(plot(df(p)*(x-p)+f(p), x=p-1..p+1, color=red), p=L); ??

@acer 

Thanks.
The same scaling that first : both axes in your example with view[ ], they starting with  0,1, .. that one i prefer.

@acer 

Thanks

Using fsolve is difficult to use for the two curves, the other two solvers are easier to use
The solver for checking for x has more then one y values is advanced
Inspecting the two curves let show the intersections . 

"If it looks awkward then I'd say that was because it is shoehorned into the books overall awkward use of Arrays to store temprary results."

Is a another store method other then a Array easier in use ?
