Hello!

I have to  solve following ODE set as a part of my MsC thesisr^2*Hr[r, r]+(r+(1/2)*r^3)*Hr[r]+(r^2-4)*Hr+2*R*(1-exp(-(1/4)*r^2))*Hi-(1/2)*R*r^2*exp(-(1/4)*r^2)*Sii-(1/8)*R*r^4*exp(-(1/4)*r^2) = 0

 

I would like download Maple 15.1. Please Help.

Hi all!

Please I'm having difficulties in specifying a repeat count for my format descriptor in Maple. For example,
If I want to repeat the format descriptor "%-+8.4f" ten times, is it compulsary that I write it explicitly as shown below?

fprintf(file, "\n%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f",e[5],mp[5],zp[5],mt[5],zt[5],roc[5],ac[5],pnloc[5],fs[5],qcode[5]):

I know in Fortran, a descriptor such as "10F8.4" is possible....

Hi everyone!

Please can some one show me how to implement the "system" command on Maple 13-Windows OS to include the specicfication of the input and output file path? I would appreciate a useful response. Thank you...

I have asked a similar question before but it appears that the difficulty of what I need to do increases when the cases are simpler.

Essentially I want to check that an expression has been fully simplified. Suppose that:

A:=2(a+b);

B:=2a+2b;

 

Is there any way to test so that

evalb(A=B) returns false?

In my case, both A and B are obtained from MathContainers:

A:=GetProperty('MathContainer1','expression');

I hope this is the right place to ask, as the links for Maple Student Help were dead. I'm trying to assign a range of values to a name in order to solve questions about binomial distribution using variations of the function shown below:

Typically, plots on a Maple worksheet fill substantial portions of the printed page when they're printed out.  What I'd like to do is resize plots, prior to printing, such that they're smaller when printed.  I'd also like all plots on a worksheet to print out at the same size.  Note that simply highlighting a plot on the Maple worksheet and then pulling the corner to resize it, is not what I want to do:  I find it very difficult to anticipate the...

 

Hello.

I would like to do 2D pointplot, where each x,y come from GPS reading, and each point have a colour dependent on z, where z is same measurement taken in each position ...

Basically, I have the code

solve([E1, E2, E3, E4, E5, E6, E7, E8], [C1, C2, C3, C4, C5, C6, C7, C8])

and I want to store each of the solutions (C1,C2,C3...) as a different variable.

How would I go about doing that? (without simply copy and pasting the solutions after hitting ENTER)

 

I thought about using

{X1,X2,X3,X4,X5,X6,X7,X8} := solve([E1, E2, E3, E4, E5, E6, E7, E8], [C1, C2, C3, C4, C5, C6, C7, C8])

but it wouldn't go through.

Hi,

I've given this problem (not exactly in this form though- therefore this is not giving the same problem again) in this forum months ago, and got a valuable suggestion.

Now, I want to take a different approach for the solution, I want to use root finding (say, fsolve ). Can anybody please tell me why the fsolve isn't working, how I can fix it ?

If possible, please send me a worksheet.  

The problem is -------  

Thank you Your more general solution works very well. I am very new to maple so still struggling with basics.

How would I get maple to display each part of the output on a line, i.e. A,B,C,D prints on seperate lines.

I am trying to compute the diffusion coefficient from the diffusion equation. I can compute the analytical solution and evaluate it for the parameters I know and for the known time t to get this function:

f:=x->
646.0548255+(309.8026777+568.8289152*I)*((.8781989023+.4782956073*I)*ln(1.+(-.8781989023+I*((-1)*.4782956073))*exp(10000000*((-1)*9.013850411)*Dif+(61.46924721*I)*x))+(.8781989023+.4782956073*I)*ln(1.+(-.8781989023+I*((-1)*.4782956073...

So basically I'm trying to slice a tesseract, with a 3D surface but first want to be able to slice a cube, with a 2D plane. so I have a 3D plot of a polygon of a face (of a cube) and I want to find the intersection of that with a plane. intersectplot doesn't seem to be working for me, and I'm unsure of how to represent a finite face of a cube as a plane

 

Heya,

I am trying to plot a graph in Maple on the (u,v) plane and I am struggling to work out how to do it.

Consider the change of variable

x=u^2-v^2                    y=2uv

Plot the lines in the (u,v) plane where x and y are constant.

If anybody could help  me in plotting this graph I would be very grateful.

Thanks.

Solve the inequality sqrt(4*x + 6) - (x^3 +7*x^2 +12*x +6)^(1/3) >=x^2 - 2.

Please help me. Thank you.
