@tomleslie thank you!!

I still have some issues regarding this subject. Please note that I just began to use Maple some days ago. 

I have two issues that I haven't been able to solve:

1)I dont seem to be able to employ parameters if they are not explicitely called. Let me draw an example:

-If I write:

>>> Explore(plots[arrow](Vector([cos(delta), sin(delta)])), delta=-Pi..Pi);

Everything works properly

-Howver,

>>> Vs := Vector([cos(delta),sin(delta)])

>>>Explore(plots[arrow](Vs), delta=-Pi..Pi);

Does not work. How can I do it?

2) I dont manage to plot multiple vectors (each with its parameters, or common paramaters with the other vectors) in the same "explore" plot.

Maybe the explore function does not admit various functions to be plotted?

example:

>>>Explore(   (   plots[arrow](Vector([cos(delta), sin(delta)]))  , plots[arrow](vector([2,-1]))   )  , delta=-Pi..Pi);

I've tried with several variations, but it does not seem to work.

Any thoughts?

Thank you

@tomleslie thank you!

@Kitonum Thank you!

However, I've tried it several times but I can't manage to get it working. The Explore window does appear, but the plot doesn't show up and returns and error (without help page assigned)

Explore(plots[arrow](Vector([cos(delta), sin(delta)]), delta = -Pi .. Pi))

This is the command I have executed. Where is the error?
