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.

I just purchased maple 14 for school. I am hoping it will help me understand how to do some calculus problems. My question is, how do I get it to work out all the steps in a problem???

I can enter an antiderivative problem and it will give me an answer to the problem, but not all the steps to answer the problem.

Thank you

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

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.

Hi!

I enclosed solution of 1D heat transfer problem which was solved by MAPLE and MATHCAD 15.
I assume exacly the same data, IC and BC.
Results are different:

Maple - wrong!

Mathcad - right!

I confirmed solution with FEA system.

Could you advice me!

I am sorry, this question is not strictly related to Maple (but could be in some sense). If I am solving some simple system of ordinary differential equations I can obtain both analytical (symbolic) and numerical solution. Thanks to condition numbers I am able to quantify the error caused by rounding (in the analytical solution). Numerical methods make approximations and errors arising from them can be also computed (and in Maple can be controlled by abserr, relerr).

Eq[1] := .1*(diff(r(rho), rho))^5*r(rho)^4*sin(theta(rho))+(diff(r(rho), rho))^3*cos(theta(rho))^2*sin(theta(rho))*(r(rho)^4-.1*rho^4)+(diff(r(rho), rho))*rho^4*cos(theta(rho))^4*sin(theta(rho))+(r(rho)^2*rho^2*(diff(r(rho), rho))^4*cos(theta(rho))-rho^4*cos(theta(rho))^5+.1*r(rho)^4*(diff(r(rho), rho))^4-.1*r(rho)^2*rho^2*cos(theta(rho))^5)*(diff(theta(rho), rho))*r(rho)

Eq[2] := p*(diff(r(rho), rho))*cos(theta(rho))^3*rho-(diff(r(rho), rho))^4*r(rho...

QuetionLinearize.mwWhen I use 'Linearize' command to linearize a equation, linm:=Linearize(...), it returns a state space or, a differential equation.

Then I want to extract the matrices of the state space, I type linm[a], but failed.

Is there any way to extract the matrices a,b,c, and d from the output? Note that this problem is different from the one which had been submitted.

If you construct the tensor product W of an m- and an n-dimensional vector space, U and V, then you can view the elements of W as m by n matrices (by picking a basis for U and V). The rank one matrices are the elements that can be written as the tensor product of (nonzero) vectors u in U and v in V; this corresponds to writing the matrix as u

My operating system is Mac OS X 10.6.4.   Lately Maple has been EXTREMELY tempermental in letting me "Save As a Worksheet"......I'm NOT talking about the "classic worksheet"

I try to save a file with a different name using "Save As A Worksheet" and Maple goes through the whole "Saving Worksheet" routine BUT NO NEW NAMED file is made!

This is very frustrating.....since it wasn't like this before.

Any ideas?

a convex  planar polygon with 9 vertexes such that every its point, which is not a vertex, does not belong to three diagonals of that polygon? This is of interest in connection with a certain combinatorical problem.
