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.

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!

Does any one know if you can extract the linear graph from a Maple Sim model?  And by linear graph I mean the alternative to a a bond graph, not a type of plot.

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

Hi,

I would like to animate solid of revolution for a region bounded by y=x^2+1, y=x, x=0 and x=2;

(a) about x=-1

(b) about y=6

Could anyone please help?

Thanks

Hi all,

I've got a parametric curve of the form f(x),h(x) x=0..1, and want to make an animation of this curve when changing an exogenous variable h0.

My attempt was to do it like this:

plots[animate](plot, [f(x), h(x), x = 0 .. 1], h0 = 0 .. 1)

but it doesn't work.

Does anyone know if/how this can be done?

Thanks,

Paul

Hi,

I want to solve the Falkner-Skan equation numbercally using maple. The Falkner-Skan equation is 

f′′′ + ff′′ + (1 − (f′)^2)=0 ,

with subject to the boundary conditions,

f(0) =0 ; f′(0) = 0,

f′(∞) = 1. 

could you  please help me to have loop to solve this problem from t=0..30.

And then save the data in DATfile in order to plot using Gnuplot?

Regards
