I have a list X:=[seq(i, i=1..8)] i.e. X:=[1,2,3,4,5,6,7,8]

Say I have a separate list containing for example t:=[2,5,6]. How do I remove these from my original list leaving me with X:=[1,3,4,7,8].

I have been trying subsop(t=NULL,X); however I only get the error message "Error, invalid input: subsop received (1, 2, 3) = (), which is not valid for its 1st argument"

I have 2 queestions:

1- concerned about the title font format:

fot the title

tit:=sprintf("W=%g,D=%g,f=%g,M=%g,N=%g,q=%a",Omega,Delta,phi,M,N,q);
                        "W=0.2,D=0,f=0,M=0,N=0,q=-10"

the little problem in the last value q=-10 it appear theta=10 even the sign (-) invisible

2- the sign(-) at the tickmars...

I use SOLVE command

>solu=solve({x+y=a, x-y=b}, {x, y});

solu = {x = (1/2)*b+(1/2)*a, y = -(1/2)*b+(1/2)*a}

>solu[1];
solu[1]

(which shows the solution value for x is not solu[1]).

I would like to use the values of x and y in SOLU to continue with some symbolic computation.

How do I recover -FROM SOLU- the values of X and Y (solutions)?

Thanks in advance,

I have a vector column XbIndets := (6,7,8) and I would like to gain the 3rd element of this i.e 8. I know it is possible using row function when using a matrix but am unsure how this is done when using a vector. 

Any help is much appreciated

Error_redirect_pa.mw  i got the problem to get repeated value of unknown parameter ''ALPHA"" using pade approximation in maple. i uploted my worksheet kind watch out my problem. and give some suggessions...Error_redirect_pa.mw 

I've seen people using different approaches to choosing random numbers.  Some people favour certain methods over others. 

One example using Sample(RandomVariable(Normal(0,1)),50) used in the random walks application.  What about using something like seq(rand(-1000..1000)()/1000,i=1..50) ?  Do they both achieve the same sense of randomness?

been struggling on this question for ages:

the questions is as follows is to be solved using maple:

where alpha,beta , sigma are constants . investigate whether it is possible to choose alpha,beta and sigma as to ensure that f is real- valued, continuous and with first and second derivatives at x=0. Plot a graph of any resulthing continous functions f and it's derivatives, over ranger -1<=x <= 1....

Hi, this is what I did and got an error.

hello ,

I have figured out how to solve for corresponding values but when i try to solve the set of equations by using for example,

a :=[10 values]

b:=[10 values]

w:= [10 values]

##here i want to solve the set of equations for  [a1 b1 w1] ,[a2 b2 w1] , [a3 b3 w1]....like i want to solve the equations for all correponding values of a,b @ each w ##

set of equations (function of a,b,c)

i cant make it work...

I am trying to assign a new value to variable. ie: replace the value of the matrix A by the matrix B.
However, when I try to use the 'new' Matrix A, it doesn't seem to be the value that I expect...

I have two vectors ( A=(1,2,3,4,5,6,7,8), B=(2,7,8) ) and I would like to compare them to see if the elements in B are also in A, and then if they are I would like to remove them from A so I would be left with the following A=(1,3,4,5,6). Is this possible and if so how?

Any help is much appreciated

I was asked to derive the corresponding first order equation by differentiating this equation but I have no idea how to. Can someone help me thanks.

The equation I have to work with is x^(1/3)*(y(x)^2+5y(x)) + 3*(x^2+y(x)^2)*sin* (xy(x)) = k

I cannot get Maple 9 Student Edistion to run in Windows 7. I've tried running it in compatibility mode, but it still doesn't work. Are there any software updates or patches available? Is there another Solution?

Hi. Why can't I print landscape from Maple?

I am trying to print my homework, which has some wide tables. The printer I'm sending to has landscape mode, and documents from other programs print landscape. But when I print from Maple, and select landscape, it comes out in portrait.

I am printing from Maple 13. The worksheet was created in Maple 14. I can print to PDF from Maple 14, but that comes out portrait also.

Thanks in advance.
