Hello,

I am new to Maple and I am interested to know what programming language Maple is written in - I mean the maths part of Maple of course and not the interface which appears to be in Java.

Thanks in advance,

Julien.

What is the Problem? Do not use SingularValues (A, output = ['list'])?
Some care in handling this command?

Hello,

I am tying to compute the wronskian of a set of functions. I loaded the LinearAlgebra package and still Maple won't recognize the following command:

wronskian(x, x^2, x^3)

Can anyone please help?

Thanks in advance,

Julien.

Hello,

I am new to Maple and would like to know how to recall the last expression in maple. Say I write "x^2 +2", then press enter and I then want to recall "x^2 +2" without retyping it. How do I do that? (I think I am in math mode using "xmaple".)

Thanks in advance,

Julien.

When integrating 1/x as int(1/x,x) the answer is ln(x) while it should be ln(abs(x)). How does one fixes this mistake?

Consider the following expression:

sCARA4 := -ln(-(mu/sigma^2)^(mu^2/(mu-sigma^2))*(sigma^2/mu)^(mu^2/(mu-sigma^2))+(sigma^2/mu)^(mu^2/(mu-sigma^2))*((exp(phi)*sigma^2+mu-sigma^2)*exp(-phi)/sigma^2)^(mu^2/(mu-sigma^2))+1)/phi;

Now try to find out whether the first derivative to mu is positive for all positive mu, phi and sigma, except for some rare exceptions (e.g. sigma^2=mu).

diff(%,mu);

Since 'is' is not a satisfying option, I used 'Explore'...

hi

please help me to solve this error.

Hey everyone.  I'm having problems solving a set of complicated PDEs.  I found a question before that helped me a bit, but the answer was less than ideal.

Here is what I have so far.

pde := [-1/4*Gamma*(Gamma-2)/r^2*G(v,r)+1/r^3*j[v](v,r)*Gamma-1/r*diff(h[vv](v,r),r)-1/r^2*h[vv](v,r)+1/2*1/r^2*diff(j[v](v,r),r)*Gamma = 0, 1/4*f(r)*Gamma*(Gamma-2)*G(v,r)/r^2+1/r*f(r)*diff(h[vv](v,r),r)+1/r*diff(h[vv](v,r),v)-1/r^2*f(r)*diff(j[v](v,r),r)*Gamma-1/r^2*diff(j[v...

Hello,

I have a plane x+2*y+3*z = 0 and a point A(1,2,3).

From A there are 3 lines :

P := (1, 2, 3) P1 := (-1, -1, 0) L1 := P+t*(P1-P)

How to find the cutting points between L1 and the above plane?

How to find a cutting points between planes? 2 3 4 planes etc.

It is urgent, please help me!

How do you map b into a to get [[a1,a2,b1],[a3,a4,b2],[a5,a6,b3]]

a:=[[a1,a2],[a3,a4],[a5,a6]]
b:=[b1,b2,b3]

Hello Colleagues:
I have tried to develop in Maple as shown in the following Gif.

What I've achieved is these few lines of commands:

I have the following script 

Download display_plot_-plot_s.mw

, where i tried to import two collumns of data from excel, what am i suppose to put after "display" to obtain the plot?

How do I evaluate moments of Q4 in a reasonable time with a reasonable accuracy, i.e. to a few decimal points:
   
with(Statistics): RV := 'RandomVariable(Geometric(1/3))+1'; R := `$`('RV', 5);

Q4 := 1/(alpha*R[1]+alpha^2*R[2]+alpha^3*R[3]+(1-alpha-alpha^2-alpha^3)*R[4]);

Moment(Q4, 1);

E.g., can I tell maple that replacing infinite series underlying this calculation with sufficiently long partial sums is okay with me? Or maybe there...

Hi friends,

I have windows 7, 64 bits, and I upgraded my maple to 64-bits version as well (Maple 13.02). But I wonder why in the task manager of windows, maple is still tagged as a 32 bits application (e.g. "maple.exe *32"  and  "mserver.exe *32")? In fact, I think the reason that I cannot run one my maple projects, which needs more than 2GB RAM, comes from this issue. Could you help me resolve the problem?

Thank you!
