Good morning everybody,

I have to make the Inverse Laplace Transformation of a function which is too complicated and the only way I have is to make it from the points of the function (I can get a plot but maple cannot get the formal form of the function because it is just too big). Does a numerical method exist in maple which can make the Inversion only from the points of the function?

Thank you,

How to plot x versus theta of the following implicit function

sin(theta)-2*sin(2*x-theta+(1/3)*Pi)/sin(x+(1/3)*Pi-theta)=0

where x is the implicit function of theta

now how can I plot the relationship between x and theta(condition:-Pi<theta<Pi,-Pi<x<Pi)

How to simplify the following trigonometric expression

sin(w t-theta)+sin(w t-theta-2pi/3)-sin(w t-theta+2pi/3)

to

-2cos(w t-theta+pi/6)

My question is a bit vague, but I hope someone can point me in the correct direction for a solution anyway. A Maple Package was been defined and placed in the Lib folder in Maple 16. The package does contain a number of custom defined functions, say Cos(v) and Sin(v) - with a capital letter to distinguish them from the usual built-in functions in Maple. After having called the package using the with statement, the new function works well in the worksheet. It also works...

Hi,

I am trying to find a better way calculating the result of an integral ===>

restart; with(linalg); with(LinearAlgebra);

 E := int(1/(1+A*cos(2*Pi*x))^3, x = 0 .. 1);

u := 1; 

F := Vector(10); 

for A from 0.1e-2 by .1 to 1 do 

F[u] := E; 

u := u+1

 end do;

now I am doing only for 10 points but normally...

Consider the following 2 sets of vectors in R^4: A = {v1, v2, v3}, B = {w1, w2, v3}. You are given that A is a set of linearly independent vectors and that B is a set of linearly independent vectors.

a) The intersection of 2 sets is the set of elements that are common to both sets. Suppose u is in the intersection of span A and span B. Determine a system of equations that could be used to determine all such

Please give specific instructions line per line, and all commands necessary to solve and plot on the same graph the inequality (x+3)^2>(-2)*(x+10).Thank you in advance for your help

For a function of one variable, I use the map command quite a bit to evaluate the function at several values of the independent variable. For example,

f:=x->x^2:

xlist:=[1,2,3]:

map(f,xlist)

How may I do something similar for a function of two variables? For example,

f:=(x,y)->x^2+y^2:

xylist:=[[1,1],[1,2],[2,1],[2,2]]:

Can the map command be used to evaluate f at each ordered pair? Maybe I'm not even using the correct data structure. Thanks!

The simplification of 1/sqrt(2) is always simplified or unsimplified as the case may be to sqrt(2)/2.  It is a matter of opinion which is simpler I suppose, but throughout mathematics teachings I've always learned cos(45) as 1/sqrt(2) as I'm sure the rest of you all have as well. Yes it is merely aesthetic, but a quirk to see it as sqrt(2)/2

Is the simplification process to get radicals in the numerator rather than the denominator?  I think yes if the answer...

Hi,

What is the command to have a programming loop record a piece of data everytime the loop runs?  I want to record the components of a vector each time.

Thanks for any help.

I would like to be able to modify the Fundiff procedure from the Physics package to generalise it for my application by relaxing some of the constraints and changing to arbitrary direction rather than just a Dirac delta function.

In order to view the code, I write:

interface(verboseproc = 2);
print(Fundiff);

I then copied the code in order to modify it. However, there appear to be some functions that I do not have access to, including Tensor and TensorSort....

I was working with the computation of the eigenvectors of a 3X3 symmetric matrix with algebraic entries and Maple 17 doesn´t give me an answer after a long time, even with CUDA activated. You can see this by the commands below:

How do I tell if the columns of A form a basis of R^5 using maple? And based on that how do I see if the matrix A is invertible using maple?

Let

A =

[ 3 1 4 1 5 9 ]

[ 2 6 5 3 5 8 ]

[ 9 7 9 3 2 3 ]

[ 8 4 6 2 6 4 ]

[ 3 3 8 3 2 7 ]

I know the answers to them but I just don't know how to solve them using maple. Please help..

Thank you

Hi,

I am working on a instability problem where I  pose my probkem as a generalized eigenvalue problem. My matrices can reach size 3000x3000. However, even this one 

with(RandomTools); with(LinearAlgebra);
interface(rtablesize = 20);

Digits := 25;
A := RandomMatrix(200, 200);
EigVal := evalf(Eigenvalues(A));

right now running for an hour but still no result. Is there a way to speed up this process? 

Can anyone explain the inconsistency in the following?
