Hi,

I wonder if you could help me. I'm trying to calculate the eigenvalues of a complicated 3x3 matrix in Maple, but I'm not very familiar with Maple syntax. The answer maple has provided me with is in the form,

(&*(sin(pi*q/P),P/T,3x3 matrix))

How do I interpret this result? The eigenvalues are scalars.

Thanks for your help,

Sian

 

 

How can i use previous inputs in new maplet window.For example i have two maplet windows; maplet1 and maplet2 I use some inputs as a functions in maplet1 and i open new window by using botton from maple1.I also want to use same inputs for calculating function in maplet2

I have a set of sets named T. How I can take all possible unions of the members of T and if the result is not in T already, include it in T. I want to do this using a seq command, but could not do. Can anyone help? This is so to say, T is to be made closed under union.

how can i preform this calculation in maple?

(∂)/(∂ log(R[e[0]]))(log(N[u]))

it's a derivative of a logarithmic expression with respect to another logarithmic expression, the one on the bottom is a "standalone" vairable and the one on the top is a function of the previous one and some others.

thaks in advance to anybody who might help.

I am using Maple 15 and when i use blew code , my system freeze!

 

n:=readstat("Input n:");
A:=matrix(n,n,0);
for i from 1 to n do
for j from 1 to n do
A[i,j]:=readstat("value = ");
od;
od;

where i have mistake?! is there any way to get an arbitrary Matrix with double for Loop? please help me! 

Hi,

I am using Maple 15 on a school server. In most of the times, the following screen occurs:

Can I get rid of that notice? My results got disappear very quickly to the TOP.

Is that something I can change or it has to be done from the admin?

And just a general question, do Maple run more or less faster on Linux/Unix machine than windows?

Hello,
I am currently conducting a study on the bridges and I need to solve a partial differential equations. However, despite all my efforts

I would like to pay attention to http://www.ams.org/samplings/feature-column/fc-2013-05 .
Comparing the Galileo's calculation 87654/53 with the capacity of Maple, the question arises:
"Are we  cleverer than Galileo Galilei?". I don't know the answer.

Hi all,

For research purposes, I have symbolic matrices of dimentions up to 100 x 50 (and above) with certain number of parameters. Then giving random value to those paramters, I want the numerical rank of the matrices.

 

Maple 17 does not seem to work well with symbolic ranks, where expentials are involved.

And more to it, both

Student[MultivariateCalculus][Jacobian]

and

VectorCalculus[Jacobian]

does not seem to work. ...

I am new to Maple (converting from Mathcad) and I am having trouble with plot3d in Maple 17.  Even in the help examples the scale numbers next to tickmarks appear blurred.   In addition after a couple of rotations of the 3D plot, my computer freezes and has to be manually reset.   I'm using Windows XP with 4 GB of physical memory.   

Would appreciate any help.  

Thanks in advance.  


Dear Mapleprimes

I am working on getting the right angles for my gears to fit together. My problem is that my fsolve (at the bottom of the page) does not seem to work. Can you help me by telling me what I am doing wrong.

By a straight forward calculation, one can check that the expressions

(2*delta^2-2*beta*delta+alpha^2-2*alpha*delta+beta^2)*N^2+2*gamma*(beta+alpha-2*delta)*N+2*gamma^2

 

and 

 

(N*beta-N*delta+gamma)^2+(N*(alpha-delta)+gamma)^2

 

are same and equal.
