I am trying to draw a triangle with black lines and fill it in gray. Based on the maple help code i am trying this code:

draw(T, thickness = 3, filled = [color = "Blue"])

It does draw the triangle T with the right thickness, but the triangle isn't filled. Any thoughts?

help appreciated

I am sorry if this was already mentioned in previous posts but I can not find it. I am dealing with plotting the solids of revolution. It is easy when you have explicit function form, for example 2-x^2. Then, when you want to rotate it around x axis and plot the obtained solid you could write:

> p := plot3d(2-x^2, theta = 0 .. 2*Pi, x = -sqrt(2) .. sqrt(2), axes = frame, coords = cylindrical):
> plots[display](p, orientation = [90, 0, 120]);

Just for fun last night I thought I'd try to whip up a simulation of the simple card game war.  The hoyle rulebook - evenly divide the cards up between 2 players facedown, turn over top card, highest card wins.  In the event of a tie the higher of the next overturned card wins (the more common variant is to play 3 facedown cards and turn up the 4th) - but that introduces more complexity to the programming ... I thought I'd tackle that later, but first ...

Hey guys, 

Its my first post, so please be lenient. I have done an internship at a theoretical physics department and part of my work was to plot a particular only numerically solvable integral over time (problem from Quantum Mechanics). I wrote a maple code and made it work, but it only produces results for certain values and even for those it takes more than one hour to plot one graph. Since this is my first big project written in maple, i assume, that the code...

This should be a simple question. But sadly I couldn't figure it out on my own

:-(

I know how to get the multivariate Taylor series expansion of a function f of arguments X[1] and X[2], about zero, and to, say, the third order,

mtaylor( f(X[1],X[2]), [X[1],X[2]], 3 );

   f(0, 0) + D[1](f)(0, 0) X[1] + D[2](f)(0, 0) X[2]

I was wondering if anyone could explain the theoretical reason (ie derive the
expression for the probability) why the optimal solution for the secretary problem
with n=100 is equal to 100/exp(1) and the probability is (1/exp(1))*100

Robert Israel tend to be good at these kind of things....:-)

The problem can be stated as follows (wikipedia):

 1. There is a single secretarial position to fill.
 2. There are n applicants for the position, and the value of n is known.

hello everybody

i want to know how can i solve this equation

64(a-b+c+d+e+f+g)=32(b-a-c-d-e-f-g)=16(7c- a-b-d-e-f-g)=8(15d-a-b-c-e-f-g)=4(31e-a-b-c-d-f-g)=2(63f-a-b-c-d-e-g)=127g-a-b-c-d-e-f

please heeelp me

Is there a way that I can plot this in Maple?

The question is:

Shade the region of the complex plane for which  (I*z-1)/(z-I)  is real.

This is real when x² + y² = 1 and (x,y) ≠ (0,1). How can I plot both of these things on one plot in Maple?

Codewords:=proc(L,x,y,z)
local
List:=[];

if L=S then
if x=1 then

print(`A 1 j k`);
else
print(`A 0 j k`);
fi:


if y=1 then

print(`B i 1 k`);
else

print(`B i 0 k`);
fi:
if z=1 then
print(`C i j 1`);
else

print(`C i j 0`);
fi:
fi:
if L=A then
if x=1 then

print(`S 1 j k`);
else

print(`S 0 j k`);
fi:

if y=1 then

print(`C i 1 k`);
else

print(`C i 0 k`);

Hi to you all, I'm brand new to this forum and I hope you could help me.

I wrote a Maple14 worksheet which perform data analysis, reading information from a set of file (usually 50 files) coming from an acquisition device. They are text file but the acquisition software produce them in the form:

namefile-0Ep.irr, namefile-1Ep.irr .... namefile-49Ep.irr

where "namefile" is the name I choose when i start the acquisition.

In order to perform...

I solve system of ordinary differential equations numerically by method=rkf45 (Runge-Kutta Fehlberg method).

1. Maple 13 installed on the Linux x64. Processor – AMD Phenom (4 cores). When Maple computes it uses only one core but other three cores stand idle. How to impel to compute other cores?
2. When I solve system of ODE a calculation reaches closely 1 ns and stops. Maple writes that value of Maxfun exceeded. But I need solve system up to 10 μs....

Hi! I've tried to figure out what to do with plot([sin^2(x),line(x)],x=-2*pi..2*pi,y=-.1..1.1,tickmarks=[spacing(pi),default});

Warning, unable to evaluate 1 of the 2 functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct.

original problem is f(x)=sin^2(x). I had to plot with the tangent line.

I played aorund a bit with the "Insert Table" command and it seems to create just an inert object that cannot be accessed or operated upon except directly by typing into its boxes. Is that true? Is it just for word processing?

Hello

i want to solve this equation

but i couldn't

please help me

( x mod 5656 = 565 ; x mod 565 = 56)

Why the command

does not return eps???

How can I simplify expressions like this?
