pls solve this

Question says: Start with the square [0,1] x [0,1] and remove the middle square [1/3,2/3] x [1/3,2/3]. Divide the part of the original square that remains into 8 congruent squares each have side of length 1/3:

[0,1/3] x [0,1/3];   [0,1/3] x [1/3,2/3];   [0,1/3] x [2/3,1];    [1/3,2/3] x [2/3,1];   [2/3,1] x [2/3,1];    [2/3,1] x [1/3,2/3];   [2/3,1] x [0,1/3];  [1/3,2/3] x [0,1/3]

Could anyone help me on how to find a median of a triangle on maple? the questions is asking for a triangle ABC , write a maple procedure which has vertices A,B, C as input and which has a out of the point P (centroid) and a plot of the triangle with the three medians.
 

Use Maple to calculate the volume inside both the sphere x^2 + y^2 + z^2 = 4 and the cylinder (x-2)^2 + y^2 = 1.  Plot both surfaces on the same graph.

I need help! I have no idea how to do this on Maple!!

Why does the second plot at the following link look odd?

I have a simple function as written below and I want to compute the partial derivative of it against an element u[k] in a vector variable u. I intentionally left k unspecified because it is not a set number and I don't really want to put it there to generate a bunch of specific output. But when I run it in Maple 12, it gives me the wrong result (sum((x-a[k])*(y-b[k]),k) instead of the correct result (x-a[k])*(y-b[k]).

restart;
with(PDEtools):
m:=(x,y,u)->sum(u[k]*(x-a[k])*(y-b[k]),k);
diff(m(x,y,u),u[k]);
 

Hi,

If anyone could help me out with these that would be great, thanks!

Hi folks, i'm ttrying to create an nxn array with n going as high as possibly 1000 to test the speed of a procedure i wrote.

Problem is, each row in the array has to have the numbers 1 to n arranged in a random order, with no number repeated.

Is there anyway to do this? Preferably using the Array command (think thats different from array...).

Cheers!

Hi,

Coul anyone help with this question?

Thanks

Your job is to test several forms of dampening coefficients to determine the ``best'' to use for safety
and comfort. You are to consider a modification of the harmonic motion differential equation
my"+ b(v) y'+ ky = 0

where m is the mass of the driver, k is the spring constant, and b(v) is the variable dampening coefficient.
For the first part of the problem, assume that m = k = 1. We will also be letting v = y' .

b(v)= v^4

Solve the ODE:

I have maple 12 and i am wondering how to approach a Newton's Method type problem. General help would be fine, but i m gonna supply a specific example that im interested in solving.

If anyone knows how to do this please respond as soon as possible, I am really having trouble with this

How the several packages for the dsolve(numeric) chose the step size? what are the criteria?
