I have a list like     K := [A, B, C, D, E, F, G, H, I];    


Now I want to remove list element K[3], K[6] and K[8] what command do I use to do that ?  remove ?

The list is much longer so manual deletion is not an option

Hello.  I am brand new to Maple.  I would like to plot complex functions, in particular as follows:  (1) I want to show all at once all the n-roots (say 4 or 9 roots) of a complex number or a polynomial with n solutions.  (2) I would like to show the results to vectors as I perform operations.  For example, I would like to display a vector, disply another vector, and display theproduct of the two vectors, all at once.

Hi,

I'm having problems with numerical integration in maple.

I've integrals of this kind

Int(6.989220000*10^12*f^(57/50)/(1.936774504*10^19+2.094942676*10^14*f^2-9.877129764*10^14*f^(107/50)+4.636748856*10^11*f^(207/50)-1.0261950*10^7*f^(307/50)+111.*f^(407/50)), f= 10...1000)

and Maple needs ages to give me a numerical answer (with value(%) ) . Am I doing something odd or it is a "normal" computing time?

I'm running maple in a 8GB RAM, 3Ghz quad core computer

Thanks

S.V.

hello

Hello everybody,

Hello, I have a 3x3 matrix in maple and am having trouble finding the eigen vector for it.

I attached the maple file. I know this is simple stuff but i am not getting the right results when i check the eigen vectors that i get.

Your help would be much appreciated.

I ran into the following error message

system error, "bad id"

what does it mean?

I am trying to write a program that contains multiple subroutine calls. I understand the placement of the single for-do loop to call the "lowest value" subroutine.

Here is program.

Calculating a given total using only given specific values

Greetings All

I'm trying to figure out a way to calculate a given total
using only given specific values.

Example:
The total given is 46

The numbers I can use are 56,38,20,12,4, and 1

I have a DAE,ODE system which is not linear in all leading derivatives or leading dependent functions. This system is really big if I use explicit=true it goes for ever.

I need to know in what way I can use (dsolve/numeric, implicit=true) to solve this system?

Due to big big big system explicit is impossible.

and due to not being linear it can not be done by implicit=true.

Could you please help me?

How can  I solve this by maple?

Thanks,

i need to plot points on 2D from text file saved on c directory

please help me

Hello, so i have been given the daunting task of figuring out what some maple stuff means in a worksheet. Now this is complete gibberish to me so i was hoping someone can kind of dumb it down for me and explain what is going on in the BOLD TYPE portion of the worksheet below. At the bottom i have also attached my maple file so you can look at it in actually maple. What the professor has asked from me is;

sum(((n+1)/n-1)*(12*n^2+12*n+1)/((1+((n+1)/n)^(1/3))*(12*n^3+18*n^2+6*n)), n = 1 .. infinity)

hello, im trying to numericaly solve this differencal equaion and i cant see what the issue is with my boundery condions. the only thing i can guess at is the bondrey conditions are ant the limits of the range im intergrating over. any help would be amazing

E := -2;
