Hi,

How are you. Nice to meet you once again.

I need your help  to give an answer to  this question:

I have two vector v1:=[1,2,3,4,5,6,7,8]; and v2=[9,10,11,12,13,14,15,16];

I would like to construct a matrix whone first colunm is v1 and last colunm is v2 and all the rest is ZERO.

Many thinks.

My old disc with the maple version 17 worked perfect, but later the disc has colapsed. So I changed the disc and installed the programm. The installation and the activation were successfull. But the programm doesn't start more. Only the command-version in dow-window. What is wrong?

I have a Text Region (made with T tool) which does contain some math elements. However, as I understand it, such a region should not be executable. When execution is attempted (by using ! with the cursor in the region), the cursor should sinply jump to the next group (executable or not). Instead, I get the following output error line as though it were an execution group and the cursor remains in the region.

Error, "=" unexpected

How is this possible?  Is there s code hidden behind the visible text that causes this?

This happens even after I copy the whole text in the region to a text region in another worklsheet.

Please, how do i compute,solve and derive d' Alembert wave formula with maple since wave=How do i derive d'Alembert formula using maple and also how to solve any wave problems eg IC u(x,0)=1/2e^-x^2 and ut(x,0)-e^-x^2 when c=4

For the following maps, determine whether they are linear transformations or not, and present an
appropriate proof.

(a) T : R^4 → M2,3 given by T(a, b, c, d) =  [a   a^2   a^3
                                                                   b    c       d ]
.
(b) T : M2,3 → M3,2 given by T(M) = M^T (transpose of M)
.
(c) T : P3 → P3 given by T(p(x)) = p(2) + 3x · p'(x), where p'(x) denotes the derivative of the polynomial p(x).

i know that the 2 rules for proving are T (u+v)= T(u) + T (v) and T (ku)= k T (u).....but how do i show it with the questions above, like do i just take any numbers , so confused

Hello,
I have some variables which usually have a specific value. I also have some parameters which are calculated using the previously mentioned constants. Sometimes though I want to change the value of the constants and re-calculate the parameters. Therefore I created a library with the initial values of the constants which I load inside a procedure which calculates the parameters. That way I can change the value of the constants and the initial values are not overwritten. My problem is that I want to export the calculated parameters and the value of the constants at the specific calculation. How do I do that_ I don't have an array, table or anything like that. Should I put my parameters in a table?

Thank you for your time.

Hi guys,

I am trying to solve for the roots in a polynomial of infinite order. The idea is simply to approximate the infinite polynomial by a high order Taylor expansion, solve for the roots in this polynomial (both real and complex roots exists) and use these roots as initial guesses for finding the authentic roots of the infinite polynomial in this specific range.

I have tried to use the evalf(RootOf(PolyInfinite=0,x,Re + Im)), however the output from RootOf seems to converge to the same 2 or 3 roots almost independent of the initial guess. Is there specific options of this RootOf function that can stabilize the solution or another/better command to use?

On the other hand i could solve this by simply minimizing a least sqaure, however i have not found any optimization solver which supports solutions in the complex domain?

I sincerely hope that you are able to help me.

Kind regards

Lasse

in maple 12

solve(a*b+a*c, [a(t), b(t), c(t)])

it return []

how to convert to a parametric form 

and then integrate them, 

and then convert parametric form back to f(a,b,c) ?

for base 10

1 op1 5 = 

        01

op1   12

_________

first digit of first number 1     = 1

first digit of second number 1 = 2

 then find 12 in logic table, it is 1, separation is 1 means move the value 1

to left 1 digit become 10

convert 10 back from base 3 to base 10, it is 3

how to construct this unknown name operator table with the custom logic table Min, Except, Diff

based on the operation described

no matter the logic table is correct or not, hope to mechanize these calculation steps for developing 3 operation table for base 10 quickly.

is it possible to develop a new kind of algebra with 3 new operators with the use of 3 operation table?

Hey, everyone!

Given the following equation: 

 I need to plot the graph when x₁ = 0.4.. How can I do that?

I managed to plot f(x) just fine, just not sure how to plot Newton'sMethod at x₁ = 0.4.

Thanks in advance! :)

E=0   f(E)=1.8  = 1/A+1    A=-0.444    kt is unknown. Hence I try many numbers.

This is my code

plot(1/(-0.444*exp(x/3)+1),x=0..9);

I have a problem.  A is negative. The denominator would be zero.

This is the theory.

If I type in a function in 2D Math, the text disappears. for example, if I type fsolve(), until fsolve, the text appears, but after i type (, the whole text disappears. How should I solve this? Thanks.

Hello,

I am very new to programming and currently i am taking a course in numerical methods which allows me to get some exercise programming mathematical functions using maple. I am trying to plot a graph and it gives me an error. If anyone can guide me i would really appreciate it.

Also if there are any helpful advise for me to start using this language, it would be a big help.

Thank you
