Hi! sorry me for my bad english =(

Can you help me with such problem? -

I need to solve a partial differential equation with 3 independent variables.

i see such answer - that maple doesn't solve such type of equations and i am very sorry about it =(

why matlab solve them and maple doesn't solve? the problem isn't hard - just give numeric solution, before i think much better about maple, and now i see that maple is rather limited program.  T_T

Hello everyone.

When doing calculations in Maple, is it possible to have Maple use some number of significant figures (as set by the Digits=n command) while only showing a specified number in the output? What I would like is a command like the displayprecision one, just with significant figures instead, so I could avoid round-off error, but still only have the relevant number of digits shown.

Thanks in advance.

Hey there,
i have a table of points that describe a rectangular function and i am trying to calculate the middle of the maximum or minimum (depending on the function) of this datacloud. my first attempt was to spline the data and then use the minimize command, however, i am not sure if the minimize command gives me the right result because it depends on my interval length. the second attempt was to calculate the derivative of the spline. but how do i get then the exact middlepoint?...

Problem of integer optimization

35*x+40*y+50*z -> min

.4*x+.5*y+.8*z >= 2

x,y,z are positive integers

When i call

> LPSolve(35*x+40*y+50*z, {x >= 0, y >= 0, z >= 0, .4*x+.5*y+.8*z >= 2}, assume = integer);
                        [135, [x = 1, y = 0, z = 2]] -- right solution

If you are interested in listing to me ramble for an hour about integration algorithms, it looks like the recording of the Webinar I gave in early September has been posted to the academic webinar archive: Theory and Practice of Symbolic Integration in Maple. I tried to make it a broad introduction for someone with...

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".

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
