i need tooo solve this asap help me

-x+y=4

x^2+y=3

I've been using Maple for many years in the good-old "classic worksheet" mode. After purchasing Maple 14, I decided to use the "new" worksheet mode (I know it's not that new, but I always objected to use it) to get the most of the 64 bit program with my 64 bit Windows 7...

1. My first problem is that "I cannot copy any output!" either to paste to an input line or to a text file!

My Tools-Options-Display section is,

Hi! sorry me for my bad english =(

Can you help me with such problem? -

I need to solve a partial differential equation with 3 independent variables.

i see such answer - that maple doesn't solve such type of equations and i am very sorry about it =(

why matlab solve them and maple doesn't solve? the problem isn't hard - just give numeric solution, before i think much better about maple, and now i see that maple is rather limited program.  T_T

Hello everyone.

When doing calculations in Maple, is it possible to have Maple use some number of significant figures (as set by the Digits=n command) while only showing a specified number in the output? What I would like is a command like the displayprecision one, just with significant figures instead, so I could avoid round-off error, but still only have the relevant number of digits shown.

Thanks in advance.

I have two transfer functions,tf1,tf2, which describing two linear systems respectively.

tf1:=TransferFunction(sys1),tf2:=TransferFunction(sys2)

Sometimes, the transfer function is very complex which contains so many symbols, and retyping them manually is very time consuming.

Now, I want to connect them in series,namely,tf3:=tf1*tf2, of course, I can extract them respectively,that is,

a:=tf1:-tf[1,1],b=tf2:-tf[1,1],then multiply a and b,c:=a*b,and...

Hey there,
i have a table of points that describe a rectangular function and i am trying to calculate the middle of the maximum or minimum (depending on the function) of this datacloud. my first attempt was to spline the data and then use the minimize command, however, i am not sure if the minimize command gives me the right result because it depends on my interval length. the second attempt was to calculate the derivative of the spline. but how do i get then the exact middlepoint?...

i am trying model my one of the problems.

i am the beginner to maple software so sometimes it become hard to do simple tasks here i have the problem

i want ot multiply u(x,y) with B where B is a 3*3 matrix but i get the answer zero,

as we all know that it will be point wise multiplication.

kindly help me how to do it.

i will be thankful if somone can give me the email for future correspondence and help.

Problem of integer optimization

35*x+40*y+50*z -> min

.4*x+.5*y+.8*z >= 2

x,y,z are positive integers

When i call

                        [135, [x = 1, y = 0, z = 2]] -- right solution

question1.3.mwI define a system differential equation, deq:=[equ1,equ2], and specifed input variable and output variable, then use command sys:=DiffEquation(deq,[A[ss]],T[m]).

Note that output variable T[m] is a delay function, T[m]=T[w](t-t[d]), where T[m] contained in equ2, and deq do not contains T[m].

When I add the delay condition T[m]=T[w](t-t[d]) to deq, and run the commands, then maple ruturns an warning:

I apologize for revisiting this question many months later. What I meant with the example was not diagonalizing but congruence. For a field that is not characteristic 2, a symmetric matrix is congruent to a diagonal matrix.

with(LinearAlgebra[Modular]);

A:=Matrix([[2,2,2],[2,0,1],[2,1,0]]);

C:=Matrix([[1,0,0],[2,1,0],[1,1,1]]);

The output is Diag(2,1,0)

The invariant in this case is 2...

example.3.mwsometimes, the system differential equations contain many parameters, such as K[t],K[a],L[a],R[a],etc.

Now, we input these differential equations to maple,namely,deq:=[...,...,...,...], of course, this input procedure consume much time.

Using sys:=DiffEquation(deq,[inputvariables],[outputvariables]) and tf:=TransferFunction(sys) yield the system transfer function.

Come under analysis, I find that a parameter, L[a...

I am using MapleNet14 on Mac OS X Server 10.6.4. 

I tried to draw 3D plot by the use of MapleNet's Image Generation.

But the following URL that is sample code from document does not

I'm in the process of reviewing Calculus for self-learning--I'm not in a class room but learning/re-learning on my own.  Would the Calculus Bundle be sufficient for that purpose?  Does it contain enough supporting information to permit self-learning?  Would steps be shown for equation solutions?

I want to find (-8sqrt(2)-8sqrt(2)i)^(1/4),

I solve it and I got this answers in polar form. (4,5PI/16) (4,13Pi/16) (4,21Pi/16) and (4,29Pi/16)

I tried this in maple, but it didn´t work. z:=((-8*sqrt(2)-8*sqrt(2)*I))^(1/4) ; ec:=convert(z,'RootOf'); allvalues(ec);

Thanks.
