Hello there,

for academic purposes I need to solve a pretty complex and substantial non-linear equation system. Here you can have a look at the equations:

kompletter_nachbau_v0.mw

The MAPLE Statement "fsolve" is not working here, though there is no error message. I know, that I can provide a framework for each variable to help fsolve find a solution. But for my usage this is not an appropriate task, since I'd like to do some simulations and variations with the input parameters.

Is there a way, so I can find a solution to my equation system?

It would be possible to make some adjustments to my equations, e.g. reducing the complexity of the equations and increasing the number of equations at the same time, if needed.

I would appreciate any advice!

Thanks in advance!

if V=(u(x,y,t),v(x,y,t),0) is vector field ( x,y space, t is time), how can find gradient of V in maple ?

iqt + aqxy + ibq (qq*x − q*qx) = 0. write this equation in maple

I did the model of the ABB IRB 120 in MapleSim, but I would like to lock several links but I do not know how to do it.

Also I need the differential equations of the robot, which must be six differential equations but in MapleSim equation extraction page there are lots of equations.

Please can you help me ?

In the worksheet below I produce a sequence of frames for an animation by distributing the task into several threads.  The result has strange artifacts as we see in the sample.  The artifacts vary randomly from run to run.  Am I doing something wrong?

Hi all,

I have a data set (see .txt file attached) to be fit to the model function A*sin(B*x+C)+D. Calculating the parameters A, B, C, and D is easy enough, but is there a way to have Maple return their standard errors?

Hi,

I can’t perform the last command (GridPlot) on my worksheet

Hello,
I am new to Maple and have some problems with fonts in Maple's forms. How can I increase the size of the monospaced font? (see the screenshot).

How would I go about getting true or false returned on these propositions?
I have tried just about every eval and various syntax methods, but nothing has worked so far.

I know most can easilly be done by hand/thinking, but I'm sure Maple should have a way to do this as well.

∀n∈Z:2n>n+2   ,   ∃n∈Z:2|(3n+1)    ,   ∃k∈Z:∀n∈Z:n=kn   ,   ∃k∈Z:∀n∈Z:2|(n+k)   ,   ∀n∈Z:∀k∈Z:(n>k∨k≥n)

Hi,

How to view all  statistical bank of data in Maple ? ( for example , Iris data)

Thanks

I am trying to find coodinates projection H(x,y, z)  of the point P :=<x3, y3, z3> on the line AB, where A:= <x1,y1,z1>, B:= <x2,y2,z2>. I tried

restart:
with(LinearAlgebra); 
A:= <x1,y1,z1>:
B:= <x2,y2,z2>:
P :=<x3, y3, z3>:
H:=<x,y,z>;
solve([DotProduct(B-A, H-P, conjugate = false) = 0, B-A = k*(H-A)], [x, y, z, k]);

I can not get the result. How can I get the coordinates of the point H?

 

I have a hard to understand quotient of multivariate polynomials- my intuition is that the denominator nearly divides the numerator - and it could be rewritten as:

remainder+(much simpler numerator)/denominator

as far as I can see the functions quo and rem aren't designed for this - but I'm certain that people in the maple community must have overcome this kind of problem before.

I am trying to run maple program in a workstation using 20-40 processor for a job. I have no idea how to do this. Thank you.

how i can solve the eqution by ritz methode codes?

For example...

Using a $2 calculator I get that rad(2470) it is approximately 49.699094.

I haven't used Maple in several months and was surprised to see that I couldn't easily search the answer to this question. Something like eval() does not work on this.
