the cylinder r = a*cos(O) cut out of the sphere of radius a centered at origin. any help. thanks

Hi everyone.

I have an assignment due in my computing class. However, I'm stuck on these 6 questions. Any help would be greatly appreciated. Please show all work, step by step. Unfortunately though, I can't use Maple shortcuts like "sum" to sum the terms in a sequence, so try not to use those.

Thanks in advanced :)

Hi ,everyone.When I entered the following code I got the error massage "Warning, solutions may have been lost." I want to solve x,how can I deal with this problem?Thanks a lot.

p := 1730;

r := .15;

mu := .17;

c := 120000;

k := 60000;

sigma := .2;

y := .89;

Hi everybody,
Using pdsolove(SyPDE, BIC, numeric), I have to model propagation of two waves , u(x,t) and v(x,t) , in two elastic test rods that are in contact. The problem are boundary conditions at the contact surfaces: values of forces and strain are equal at the first rod right end and at the second rod left end:
D[1](u)(l_1,t)=D[1](v)(0,t) and (u)(l_1,t)=(v)(0,t)
Maple can't do that. Should I put in code some transitional Maple expression or function for force and strain, like, for force X:=(delta*x)/l, in order to get this:
D[1](u)(l_1,t)=X, D[1](v)(l_1,t)=X,

Hey, does anyone here know how to program the product Nystrom method for solving integral equations of the second kind? Thanks

Dear all:

suppossed i have a function as following :

f(x):=2*sin(x)*(sin(x)+I3*sin(3*x)+I5*sin(5*x))

where x is belong to (0,Pi/2), I3,I5 is defined to I3^2+I5^2 < .232.

i have ploted some curves of f(x) . As to different I3 and I5, the curve of f(x) have different point of intersection with y=1 function, may one point or two point or three where 0<x<Pi/2.

hi,i am new to this and when i start up maple 12 i get the following error:"Java Virtual Machine Launcher, could not create the java virtual machine".

Hi,

I have a problem with define(f,multilinear). I want that Maple threats alpha[i,j] as a constant such that f(e[1], alpha[2, 4]*e[4])=alpha[2,4] f(e[1],e[4]). I've added all the alpha[i,j] to the constants, but still, he fails to compute f(e[1], alpha[2, 4]*e[4]).

It works when I add alpha(i,j) to the constants, but then the rest of my program doesn't work, so it really should be with [,] and not with (,).

Thanks!

I've recently updated to Maple 12 (on Mac OS X.4.11) and am still learning how to use it. A search on Maple FAQs didn't turn up any answers to the following questions.

I am posting it again. I need the plot of W(i+1/2)=1/2*(W(i)+W(i+1))+1/2*sqrt(sagma*t)*g(i) where g(i) is an independent N(0,1) sample. Please some one help. i have attached a file of the plot which I need.

In my 3 D histogram the colums have a 1*1 base, so normally they would be labeled 1,2,3,4,5 on the x and the y axes but instead of this I want to label them 0.25,.05,0.75,1,1.25,1.5 and so on..........
Is there a way to do it?

Hi experts,
I created a 3D histogram
with(plots); with(LinearAlgebra); A := [[2],[3],[3],[4]]; matrixplot(A, heights = histogram, labels = [c1, c2, ExpectedProfit], tickmarks = [spacing(2), [seq(i, i = 0 .. 8, 3)], default], axes = normal)
Now I want to assign a colour to each column. When the value is 2 of the Matrix it should be red for example, when it is 3 for example yellow and so on. Later Later I want to expand it to a Matrix with B[n,m]n=10 values...
Thanks alot in advance for your help!

Hi to all,

I am new to maple. I want a maple procedure for the following Boundary values problem.

Thanks

I installed maple 12 as root user successfully. But sometimes simple command like

1+1 or any command takes a long time to complete. After a long delay maple

displays result. It's happening very often and it's annoying. I'm using Debian

Etch, kernel 2.16.8-custom.

Hi Everybody:
I've a question about "convolution". How can I afford the convolution of different scaled functions?...
In Example: F (2*X/T) in convolution with G ( X/T ) ?
Is this equals to : Int ( F(2*w/T) * G((X-w)/T), w=-infinity.. infinity)?
Am I wrong?...
The particular problem is :
Convolution of ( T*Triangle(2*X/T) ) with ( shah( X/T ) ),
with Shah (x) = Sum( Dirac (x-n), n= - infinity.. infinity).
Thanks for helping!
