## How do I prevent Maple from displaying t...

Maple

I think the question speaks for itself. I tried the search engine and he bring me one link on that subject. But when I click on it, he sent me inside many answers on everyting but that. Not even the right month. So that is why I am asking here again. Of course, I would like to keep the thickmarks and the labels on both axes. Thank you in advance for your help.

## Combination of two sets...

Maple

I have the set A := {12, 17, 24, 28} and the set B := {358, 568}. I would like to do the combination (at least that is the name I think I should use) of the two sets to get the following result:

{12358, 12568, 17358, 17568, 24358, 24568, 28358, 28568}

As a bonus, if it's not too complicated, I would like the procedure to see that there are two numbers that have repeating number in them. In fact, the last two elements of the result, namely 28358  and 28568 has two 8. So those last two terms should not appear in the result. We should get only the 6 elements {12358, 12568, 17358, 17568, 24358, 24568}.

There are so many possibilities with Combination and Iterator that I am lost in how to do it. Maybe someone has had to do it before me and have an idea on how to do it.

Thank you in advance for your time.

## How do you do the wedge product of two v...

Maple 2023

I am starting a course on differential forms. They have introduced the wedge product by comparing it to the curl product. I can do it by hand. But I would like to do it in Maple. I tried to read the help page of with(difforms) but I cannot see how to do it. And to add to the complication, since my keyboard is in French, I don't know how to insert the circumflex accent right after &. Maybe I should just wait that more theory is done, but just for the principle, I would like to be able to do it. For example, the vectors are:

a=(1, 3,-2)

b=(5, 2, 8)

Thank you in advance for your help.

## Manipulating the coefficients of a polyn...

Maple 2023

I have this equation:

and I need to do some manipulation to obtain this:

I manage to get it but my manipulation is too long for my liking. Can someone show me a shorter version. I have linked the Maple document.

## Problem getting a plot the way I want th...

Maple 2023

Below is the plot like I want it. The basic plot has been done with a simple plot command.

>plot(0, x = 0 .. 10, y = 0 .. 4, gridlines = true)

But the label of each axis was done manually. But I have tried to do it inside the plot command. A little help would be very appreciated.

So here is what I want the plot to look like:

Thank you in advance for the help.
