Hi,

Can anyone please suggest a way to set the zoom factor for a 3D plot from the plot commands or using DocumentTools or in some other way that doesn't involve the interactive tools?

What I'm trying to achieve is the following:

I'm developing MapleCloud worksheets for a course I'm teaching and want to give my students several 3D plots to interact with through their web browser.  When I make the plots, Maple determines the scaling so that boxed axes with labels will fit in the area of the plot component.  However, I'm making plots with axes=none that look better at a higher zoom factor (the corners of the unseen boxed axes would be out of the plot area but all the plot components still fit) and I'm keen to create the plots that look like this if possible.

My ideal solution would be for there to be a zoomfactor option for the plots[display] command or to be able to use some code like SetProperty("Plot0",zoomfactor,1.25) but I haven't been able to find a way to achieve this.  The closest I found was setting the viewpoint option, but that locked the view, preventing rotation, and I want to just set the initial view.  Is there some other method I haven't found?

Thank you for your help,

Alex

Hello,

In order to improve the readability of a worksheet, I would like to insert in text lines the equations that I calculate after with a input maple.

Question:

Is it possible to add in a text line equations and symbols as we can make with Latex or MathType ? For example, i would be interested to write vectors in a text line.

Thank you for your help.

I get the maple result as a product and sum off terms

x= (a+b*c)/d

i want to convert it to

x= a/d+b*c/d

i try to use convert(x,?)  

I am trying to find a general solution to the 1D-wave equation

Eq1:=diff(u(x,t),t$2)=diff(u(x,t),x$2);

pdsolve(Eq1,HINT=f(x)*g(t)); # Hinting pdsolve gives general solution using separation of variables

pdsolve({Eq1,u(x,0)=f(x),D[2](u)(x,0)=g(x)}); # without HINT and using intial conditions, I get travelling wave solution

pdsolve({Eq1,u(x,0)=f(x),D[2](u)(x,0)=g(x)},HINT=f(x)*g(t)); # Now when I try to use hint and ICs both, pdsolve return nothing.

I want to use separation of variables to find solution to the wave equation.

Any comment?

Thanks

A := Vector([1, 2, 3])

solve(2*A = 5+x, {x})

can anyone help me why i am having proble to solve for x?

Thanks

It returns unevaluated.  The solution is x=-ln(3),y=0.  In fact it doesn't give a solution even if the solution is provided as the initial point.  The value of Digits doesn't seem to make a difference.

(Tested Maple 2015.2 Macintosh and Maple 2015.1 Linux)

Hello

I am new to maple. If i have a vector from 0 to 1000 every 10 step (in matlab it is sth like this x=0:10:1000) can anyone help me how to do this in maple?

thanks

Salut j'ai fait un programme avec maple   pour minimiser une fonction à deux variable avec la méthode de fletcher reevers car la fonction minimize ne marche pas avec les fonction plus compliqué.
SP veuillez voir mon programmme et essayer de le corriger car la boucle while ne marche pas:

Hi everyone

When I solve these nonlinear ODEs, there is this problem i.e. Highlighted in yellow, in my solution. How can I solve it?

thanks a million!

nonlinear_ODE.mw

with(Student[LinearAlgebra]);
example1 := Matrix([[1, 2, 3], [4, 5, 6], [6, 7, 8]]);
whattype(example1);

testproc := proc (A) print(whattype(A)) end proc;

testproc(example1);

The whattype() calls output:

Matrix
proc() ... end proc

I don't understand why what is a Matrix type outside the procedure seems to change into this unrelated type? This is really bizarre. I feel like it may be something outside my code? Thank you.

Hi,

I'm trying to use Maple to plot a dependence, but Maple says there is a singularity.

Attached is the Maple file I'm using (Equation 2 and the 2 graphs pertaining to it are the problem)

They should look like the attached graph, but since Maple claims it hits unity, it won't plot any further points.

Is there a way to override this to force Maple to plot after reaching a singularity?

Any help or advice would be very much appreciated

Thanks,

Dear maple users,

I have a lengthy formulation of function f(x) which contains some constant coefficients (A₁, A₂, A₃ ...). I would like to simplify f(x) for functions of same above mentioned coefficients as following:

f(x) = f₁(x) A₁ + f₂(x) A₂ + ... + f_n(x) A_n

I tried the following command:

collect(simplify(f(x)), [A₁, A₂, A3 ...])

Maple returns the expected form of functions but the problem is that Maple did not simplify f1(x), f2(x)... Obviously, I do not want to simplify manually : simplify(f1(x)) ... again

How can I solve this problem?

Thankyou.

Hi all,

I have a function f(x) and want to know at which x-value it attains its supremum.

Tried this, but it doesn't work (or at least hasn't been able to solve the equation in 10+ min):

M := maximize(f, x = 0 .. 1);

solve(f = M, x);

Does anyone know a way to do this?

Thanks,

Paul
