I used to be able to do this copy/paste ... Here, I got an integral, then copied the output and pasted onto the next line. I wanted Maple input format, of course. Is it a change for Maple 10.03? for Mac? Or what? Have I got some setting wrong?

Dear colleagues: I am interested on taking some data from serial Port (Com 1) to process them with Maple. Can you give me some suggestion, library or anything that could help me? Greetings Somos4maple

I've been using Maple 9.5 on my mac for a while with no problems. Then last week my delete key stopped working. I can still highlight and delete but I can't delete straight text. Does anyone know what's going on with my Maple? Thanks!

If I attempt to evaluate the integral int(exp(I*z*cos(x)),x=0..Pi), I should get a Bessel Function, in fact J_0(x). But Maple does not do this, the way I use it. How does make maple10 recognize such integrlas?

To my fellow maple user: I wanted to label critical point/s in plotted curve. For example: plot y=x^2 + 5. P(0,5)is the vertex. I like to label this point as "Vertex" on the plot itself. Thanks in advance for any assistance. pv

Hello, I was hoping someone could suggest a way to add a index counter to the title of a Maple plot. I have some snapshots of an animation that I wish to include the value of the for loop/index counter in the title. Does anyone have any suggestions? I am using Maple 10. Thanks very much for any help, sbh.

I would like to solve the following problem as stated below:

> ode3:=J=diff(E(x),x)*E(x)-diff((diff(E(x),x)),x);


> dsolve(ode3);



> odeplot(dsolve({ode3,D(E)(0)=2,D(E)(1)=2000},numeric,range=0..1),refine=1);

Error, (in dsolve/numeric/BVPSolve) initial Newton iteration is not converging

I have taken "J=2" doesn't matter too much for now. As you will see from the second command Maple can find an analytical solution to the problem. From my trials it seems that the initial condition D(E)(1)=2000 makes the problem, smaller values are ok. I have tried "Digits:=100" but this didn't help me. In the end it would be nice to go to larger (about 7 orders of magnitude) values for D(E)(1) in comparison to D(E)(0). Can you help me find a way to solve this problem?

To anyone: Please provide the syntax on how to substitute without maple evaluating the expression. For example if I have an expression x^2+2x+5. I want to substitute to the expression x=2. I want simply to see 2^2+2*2+5 without Maple evaluating the result preferably in maplet form. Thanks PV

Hello.

Can anybody explain me please this error? Thanx :-)

Error, cannot determine if this expression is true or false:

-2.500000000*exp(0.) <= -1.675000000

Here's a frustrating problem I've been having with "assume".
You'll see below that I assume that v'(m) >0 and v''(m) <>
Maple clearly remembers that v'(m) > 0 (as seen in the assumptions list and by looking at the first "is" in (4)), however, it now can't figure out that v'(m) > 0 implies !(v'(m) <>
Strangely, this worked perfectly fine before the additional assumption was added, and looking up the property (6) reveals the correct answer.
Moreover, maple seems to have two sets of assumptions on v'(m) (for six total assumptions, when I would expect four).

Any maple geniuses have an idea as to why Maple's "is" function is confused?

Implement a computer program which, for a given lower triangular matrix A with the diagonal entries different from zero,finds the matrix inverse to A by solving the equations Axj= ej for j=1,...,n by the " forward substitution"

Implement a compter program which decides whether a given matrix A e Mn is symmetric positive definite.

Implement a computer program which, for a band matrix A eMn with p=3=q such that the non zero elements ofA appear in the main diagonal and in the diagonals on the boundary of the band only,for a vector b e Rn and for w e(0,2), e>0 given, approximates the solution of the system Ax=b by the relaxation with accuracy e.

The feature which allows users to copy and paste the equations from Differentiation or Integration Tutor is disabled after i install Maple 10.03 update This feature is useful for lecturers as well as students. I wonder could Maplesoft enable this feature in the coming update. Thank you.

Could anyone please suggest how to data cluster analysis? I have a large set of multi-dimensional data (300 children prefer 2-3g of sugar in their breakfast cereal, whereas only 100 prefer 1-2g, etc) and I want to break the data up into blocks that minimize the number of different types of cereal I should create, while capturing the maximum amount of the market. I expect there is some least-squares way of doing this, can anyone suggest a concrete example of how to this in Maple10? Thanx
