These are questions asked by lemelinm

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.

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.

Thank you in advance for your help.

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.

Hello Maple users,

I have the following metric:

In the calculation of the different tensors, I encounter the derivative of "v" w.r.t. "t" and "v" w.r.t. "r". Can I use the compactdisplay command so that the first derivative is with a dot over "v" and a prime beside it for the second derivative for r (or other symbols, as long as it simplifies the output.

Here is my General_metric.mw:

Thank you in advance for your troubles.

I would like to write this equation:

That is a symbol that I want to be able to use (the S can be added after inserting the symbol). Sometimes, this helps the students to comprehend what they are doing. It could be added the symbols for double and triple integral. So it is some kind of suggestion, but for the moment, it is the actual symbol I would like to have.

I think that I could write it in LaTeX but I don't know if I can do it in Maple and ask him to convert it inside the document.

Thank you in advance for your help.
