Hi,

How I do to run the commands of the package  in Maple 13?

Gracias

For some reason Maple just will not solve this...

2.160417096*x^(2.513) + 0.9921351694*x^(0.512) -15.95645167 = 0

It runs for about 10 minutes before I decide to give up.

The only thing I can think of is I had one of those 'lost kernel' messgaes the other day and I closed Maple while it was trying to restart the kernel so maybe that caused some problems with my system...

 

 

I want to factor the 34 th Fermat number.

F(n) := 2^(2^n) + 1

I can enter the 29th Fermat number: 2^(2^29) +1, and Maple will evaluate it.

I seem to be under the maxdigits limit:

>	kernelopts(maxdigits);

 

Hello Friends;

How could make maple show me the steps and rules applied in the following exerted?

3^(-2*x^2)*9^(-2*x^2-3) = (1/27)^(6*x-2);

Something very similar to the command:
Student[Calculus1][ShowSolution]
Thanks

 

I'm getting started with this. I'm reading books about General Relativity. Their notation uses superscripts and subscripts in Greek, for examples. But in the lessons for DifferentialGeometry and in applications I find in the Maple website, I see coordinate systems of (x,y), for example. Indices, raising and lowering, and other operations involve "d" and "D_" notation. Examples use something like T12 to represent what I would want to see as "T" with two subscripts having values of 1 and 2. I apologize if I'm not explaining the background to my question well.

Hi guys,

I am not a experienced user of Maple. So the question is probably very basic. Any help is appreciated.

I have 2 coupled first order linear equations. I may be able to solve them manually, but I thought it would be a perfect application for Maple. The problem is that I have no idea how to do it in maple. So here it goes.

d(y1)/dt = (a-y1)/T1 - k1*y1 + k2*y2;

d(y2)/dt = (b-y2)/T2 - k2*y2 + k1*y1;

Under the following constraint: a*k1 = b*k2;

How may I solve this problem in Maple?

 

Thanks a lot.

 

Using a loop to put values into a double indicie, the output table is not organized.

for i from 1 to 4 do
  for j from 1 to 3 do
    a[i,j]:=5*i;
  end do;
end do;

print(a);

table([(3, 2) = 15, (3, 3) = 15, (4, 1) = 20, (4, 2) = 20, (2, 2) = 10, (1, 2) = 5, (2, 1) = 10, (1, 3) = 5, (1, 1) = 5, (3, 1) = 15, (4, 3) = 20, (2, 3) = 10])

hey, I've made a almost all  of my mechanics work during the past year in a single Maple document. Now, for som reason, the document wont opendue to "There were problems during the loading process. Your work sheet may be incomplete" please help my, I would really hate loosing so much work...

Btw. mapleprimes wont let me upload the failed file so if someone could either post a guide/torturial or there email I would be vey pleased.

Hello, recently I am working to write a bash shell program combined with maple to automatically produce the codes to calculate functional and functional derivatives values for some given functional expression(This is provided by the user in maple input file). Now I meet a problem.

Take the codes below as an example:

I have written a procedure.  Without going into details, here is the pseudocode of the procedure:

time:=proc(begin,end,c,deltaT)

t:=0;
v:=0;
accel:=5
where-we-at:=a;

while where-we-at =/= end do

distance:=*distanceformula*;
where-we-at:=*where-we-at* formula;
t:=t+deltaT;
v:=someformula;
accel:=accelformula;

end do;
return(t);
end proc:

 

How do I create an exptression with absolutely no evaluation?

I would like my students to practice the order of operations, so I want to be able to display an expression without evaluation of any of the operations involved. Is this possible somehow?

Hello,

I have a ode system which I use dsolve/numeric for it?

By default dsolve use rkf45 but the result is not very exact. The error is high.

How can I make dsolve more accurate?

Which method I have to use?

It is initial value problem that I use dsolve/numeric for it.

Thanks so much.

Bye

Not sure how to do these problems with maple.

I need help making a 3D plot of a numerical solution to Euler's Equation for Rigid Bodies(Non-linear Differential Equation). The solution to this equation are the angular velocity components w1,w2,w3. I am able to plot each component using the following commands, plots[odeplot](numericalsol,[t,w[1](t)],0..20); plots[odeplot](numericalsol,[t,w[2](t)],0..20); plots[odeplot](numericalsol,[t,w[3](t)],0..20); However, how do I make a 3D plot using these numerical solutions?? Any help is greatly appreciated.

Sometimes I've seen manipulations like this:

dx/dt = dx/dy dy/dt

in which the symbols of the derivatives are multiplied and cancelled like terms in equations. I can't remember nor find the justification for doing this. What's the explanation?

I can't get Maple to do this for me. If I make x an expression of y and y an expression of t, then it substitutes the expressions into the arguments, and I get a nonsensical result:

> y := t^3;
3
t
> x := 'y^2';
