I am currently working on a MapleSim model that is similar to the Stewart Platform, yet less complex. I have built a tripod that is fixed to the ground with three legs connecting to a platform. Connecting the leg to the ground is a revolute joint and connecting the leg to the platform is a spherical joint. When I change the initial conditions of the spherical joint from 'Treat as Guess' to 'Ignore' 2 of the 3 legs will change orientiation. I'm not sure why this occurs to only 2 legs, can someone help me?

Let G be a connected undirected graph. How to find the minimal set of the edges of G, such that its annihilation transforms G to a planar graph, with Maple? The procedure should work with big graphs.

I want to integrate the following two function using Maple, but it returns nothing

When I use ImportMatrix to import a MATLAB mat file, I get a list of names and values. Should I write a "for" loop to assign them in Maple or there is an easier way to do it?

i would like to nknow how can i eval a function wiith a matrix?

I have obtained the taylor series expansion of a function and got the coefficients as numbers.

I want to assign those coefficients to a variable.

I need your help.

Hello,

I'm quite new in Maple and stuck at one point. I think it is a trivial but I'm stuck anyways and hope somebody could help me here.

Following the DE system i'd like to be solved.

I am trying to determine if a particular system of 15 polynomial equations in 9 variables has a real solution using Maple's RegularChains library.  I am using the IsEmpty command which returns true if there are no solutions and false otherwise.  In Maple 16, this can be done using the command:

IsEmpty( sys, R ) ;

where "sys" is a list of equations and "R" is a polynomial ring, both of which I define in the worksheet.  But this syntax only works...

I need to keep parentheses surround some expression, e.g. (2x+1). However, Maple removes parentheses. Is there a way to keep them?

is there a maple function or does anyone have a proc that will return the number of significant figures given a number? For example, when given 0.38, the proc will return 2, or when given 2.897, the proc will return 4.

Hi all. I am trying to find the cube roots of -sqrt(6)-sqrt(18)*I in polar form. I have used the following commands but it does not convert the argument properly. Can anyone help? readlib(polar); sola:=solve(z^3=-sqrt(6)-sqrt(18)*I,z); polar(sola[1]); polar(sola[2]); polar(sola[3]); I have also used the following but it could not simplify the argument/angle. sola1 := simplify(convert(sola[1], polar)); Can anyone please suggest a fix to this? The argument...

Hi, anyone can show me how to expand this formula with Maple:

                            (x+1)^n

where n is an unknown integer. My expectation is x^n +n*x^(n-1)+...

 

Thank you and regards,

Dear Maple users

I am working on importing data from an Excel-file "Data.xlsx" into Maple. This is done using the following commands:

> restart;
> with(ExcelTools);
> X := Import("Data.xlsx", 1, "A3:A63");

One strange behavior is the fact that I receive an error message: Error, (in ExcelTools:-Import) Could not open the file.

When I close the Maple file and open it again and reexecute, the error disappers and everything works....

I have created a wheeled robot in MapleSIM for my bachelor thesis and for various calculations I need the location of the center of mass.  I am unsure of how to find this.  Could you please help me and explain how to find this?  Thank you for your help.

I have got the following instructions of computing the required trajectories (orbits). They have been done with Maple V3. I cannot get them going with Maple 16. I have just started with Maple and cannot see the mistake in the instruction. Can anybody help me? Thanks!
