In particular, Maple contains the Logic package, which is useful in teaching. But I do not understand the outputs of the Normalize command. Here is an example:

>with(Logic);

[`&and`, `&iff`, `&implies`, `&nand`, `&nor`, `&not`, `&or`, `&xor`, BooleanSimplify, Canonicalize, Contradiction, Dual, Environment, Equivalent, Export, Implies, Import, Normalize,
 Random, Satisfy, Tautology, TruthTable]

>f := Random({A, B, C});

Hi,

I tried to start a daemon for Maple 14 in Ubuntu 8.04 OS, but when I try to run lmgrd,it says that there is no such file or directory. Can any one give an idea on what the problem is and how to over come it.

Below are the output of few of the commands.

1)O/P of command "file lmgrd"

appmath@appmath-desktop:~$ cd /root/Maple_Network_Tools/FLEXlm/11.7

Is it possible to change the font size of the Maple output?

And if yes, how?

When I simplify the following two (to my mind identical) expressions, I get different outputs. But why?

s1:=exp(ln(((mu)^(2))/(sqrt(((sigma^(2)))+(mu)^(2))))+(1-phi)*ln((sqrt((((sigma^(2))))+((mu)^(2))))/(mu)));

simplify(s1);

and now just replacing sigma^2 by sigma2 gives:

s2:=exp(ln(((mu)^(2))/(sqrt(((sigma2)))+(mu)^(2))))+(1-phi)*ln((sqrt((((sigma2))))+((mu)^(2))))/(mu)));

simplify(s2);

Hi friends,

It is a simple question but I got confused... The best way to explain the problem is the example below (I modified my example to make it more clear and easier):

gCount := 1;

hCount := 5;

dCount := 10;

lineCounter := 1;

for k to gCount do

  for i to hCount do

    for j to dCount do

Hi, im Gabriel from chile, and probably my english wouldnt be very good :P.

Im working on a problem that needs to be solved numerically, its a set of coupled non linear equations. Im succefull in finding the solution given a set of initial conditions, but the problem I have is when I try to save those solutions.

I want to save them in a .m file to fully recover it when I start the session again (it take some time in find the solution, and I have to iterate the...

I have three diferential equation each one is single ( there are no coupled)

I want to solve each one and compare their solution I would like to  plot solutions in a same graph. How can I do  so ?

My problem is

Hello, I need to know how to graph in Maple as follows:

the plane 2x + 3y - z = 5 and the cylinder x ^ 2 + 4y ^ 2 = 9 x ^ 2 + y ^ 2 = 1.

The idea is to plot everything in a single graph, as shown in the books of calculation.

I have tried in various ways, but I do not go away.

Dear Maple Users

I know how to create 3D plots of geometrically defined objects in Maple. One can rotate the plot by plain dragging. What I would like, however, is to make the same thing happen on my website. Is it possible to export the 3D plot into some file format and embed this object on a website? They have done it on this page:

I tried to solve the following nonlinear equation system:

with(Statistics):

Y9 := RandomVariable(LogNormal(a, b)):

solve({mu=Mean(Y9),(sigma)^(2)=Variance(Y9)},{a,b}, UseAssumptions) assuming a::real, mu::real, sigma>0, b>0;

The problem is that the conditions, which discriminate between the cases of the piecewise solution are puzzling, not to say impossible to meet.

E.g. at the end of the first row it says:

hello, I make some code about NURBS.

Till NURBS curve and surface I did. These shapes are came from parametric equation.

Nurbs curve is...

plot([F(t),G(t),t=0..1]);

and NURBS surface is

plot3d([F(t,p),G(t,p),R(t,p)],t=0..1,p=0..1);

so I tried to make solid also by using 'implicitplot3d'.

But it does not support parametirc equation.

For example, implicitplot3d([F(t,p,s),G(t,p,s),R(t,p,s)...

I try to solve a nonlinear ode system. in numerical calculation it always calcualte the second derivative of my variable zero, while in the plot of the first derivative on the variable it shows that the second derivative has not to be zero

here is my problem:

My variables are a(t), phi(t). Bty solving the system of ode1 and ode2 and plotting a(t) and its first and second derivateive we see that its second derivative is always zero whime from the graph af its...

I want to differentiate the following (example) sum with respect to each variable.

foo:=sum(x[i]^2,i=1..3);

By hand I solved it like that:

g1:=diff(foo,x[1])=0;
g2:=diff(foo,x[2])=0;
g3:=diff(foo,x[3])=0;
solve({g1,g2,g3}, [x[1], x[2], x[3]]);

This works for i=1..3 but later I want to have it approach infinity. I don't have that much time to do it by hand -- what's a cleaner solution?

I would like to express a matrix in a neat(er) form.  For example, both matrices;

Matrix([[1/4, 1/2], [1/2, 1/4]]);

(1/2)*Matrix([[1/2, 1],[1, 1/2]]);

return the same thing.  I would like maple to print the latter with the factor 1/2 preceding the matrix for better clarity.  Is there a simple command that will do this?

Cheers in advance.
