Hi friends,

I am using contourplot / contourplot3d for a function f(x,y). But the coloring accepts only two colors whereas I want to get a contour like the one which is shown here  and is more common in most engineering applications.

My second question is how I can change the size of the plotted graph, because I am using the results in a report, so I need to have a better resolution.

Thank you!

The procedure p gives an approximation for Pi. Idea is to place a unit circle in a unit square, throw in some random points (which eventually will be plotted into this figure) and count the points inside the circle. For large n, the quotient n_circle/n_square should tend to Pi/4. But for large n, there may be faster ways to program this, what would you improve ? But keep the principle of this algorithm as it is.  I'd love to have at least 200k points, but this takes annoying 25s on my machine on each run....

I need to calculate the following conditional expectation

with the marginal density

and

being the density function of a normal N(mu, sigma) distributed random variable

I tried to solve this problem. 

It is a Maple TA question, but I get my solution wrong.

Question:

There is given a linear equation system consisting of two equations with four unknowns.

hello
I am doing something about curve fitting. I have got a polynome, I want to have it differentiate on the coefficients A,B,C,D,E,F, then all of these results will be set to zero. so I get 6 eqs,I want to use this 6 eqs to solve the coefficients A to F.  x0,y0,z0 is the coordinate for certain dot. I write the orders as follows:
eq :=(A*x0^2+B*y0^2+C*x0*y0+D*x0+E*y0+F-z0)^2;
S:=map2(diff,eq,[A,B,C,D,E,F]);
solve(S,{A,B,C,D,E,F});
but I got the answer

Hi friends,

is there a way to convert a Maple 13 worksheet into a Mathematica 7 Notebook automatically?

Thanks for help

Working in Calculus Study Guide which uses EpsilonDelta maplet in examples and problems. Study Guide says to enter epsilon and delta values in fields at right, or to use sliders. Sliders function for rough work. However, fields displaying vlalues are grayed out and do not accept entries. Difficult using sliders to get precise small values. Is this a program error or something I am overlooking? Thx.

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);

>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.
