I've been making some use of the Maple Cloud for a while now, and thought that I'd share some comments.

So far, it's been quite useful to me, and I like it. This surprised me a bit. I expected not to find it useful, and to dismiss it with an old-timer's "Bah, humbug... as useless as Maple+twitter!" But, to the contrary, I've found a use for it; a need that isn't otherwise...

I'm in the process of reviewing Calculus for self-learning--I'm not in a class room but learning/re-learning on my own.  Would the Calculus Bundle be sufficient for that purpose?  Does it contain enough supporting information to permit self-learning?  Would steps be shown for equation solutions?

Hello,

I have some problems with pointplot3d command. This text worked in Maple 12 but it doesn't work now...

I have got this "Error, (in plots/tolist) points are not in the correct format".

My text:

It's a new school year and traffic is up.  Just wondering what happened to the student maple forum?

Also as a suggestion, some forums have sticky's, a post that stays at the beginning of the forum where users can generally find welcome information and helpful starter hints, yes it's impossible to cover everything but something would be nice for the new users. 

Is there a way to insert a table of content with the headers of the sections at the beginning of the document? (like in MS Word)

If I click on the link, maple should jump to the section.

It should be updated, if I create a new section or change the header.

This is the continuation of the question . We have a convex polygon with 9 (a natural number n>3)  vertixes  such that every its point, which is not a vertex, does not belong to three diagonals of that polygon. The question is:
how to count  the number of the sets of the polygon partition by its diagonals?
I have in mind a Maple procedure, not the formula. The answer is 154.

how to use delta operators OR basic  finite difference methods in Maple?

Please guide me

Δ² f(x) where f(x) = x⁴ , h=1

Hi,

I am a student brand new to Maple.

How can I add a newline in a Maple Input block in Document mode?

Whenever I hit Enter, the code I've typed up to that point - which may be incomplete - is executed. Or, I may need to add a line to some code given to me, but pressing ENTER tries to execute it. (And where in the help system could I find something like that? I looked, but couldn't find it).

Thanks

Hello,

This is my beginnig with maple. This program seems to me very cool, and handy in my study. But I have problem. I want to create a document of project where are simple things but I don't how force maple to show counting.

In maple I do:

x:=5

y:=8

x + y = 13

But I want to show how it was counting I want sth likde that:

x + y = 5 + 8=13

I was looking how to do it but I can't find anywhere.

Please could anybody help?

In the chemical and oil & gas industries it is quite common to describe a gas flow in units of standard volume (e.g. normal cubic meters aka NM3 or standard cubic feed aka SCF).

This is really equivalent to a molar flow rather than a volume flow since the volumes are calculated based on the ideal gas law assuming the flow is at standard conditions (1 atm and 0C for NM3 and 1 atm and 60F for SCF).

I would like to add NM3 and SCF to the SI and FPS unit systems.

There is a difference between a variable with an index and a variable name with an index in "2D Math"-Mode.

The variables look similar.

Here an example, what I type and what I get.

a (SHIFT + _) 1:=2

a (SHIFT + CTRL _) 2:=3

a (SHIFT + _) 1 * a (SHIFT + _) 2

a (SHIFT + CTRL _) 1 * a (SHIFT + CTRL _) 2

a (SHIFT + _) 1 * a (SHIFT + CTRL _) 2

And this is, what I get.

I want to determine the domain of definition for an expression using a command,

but i can't find it in the help,

can someone help me,

thanks in advance.
