Hi, I'm trying to calculate a few integrations:

E1:=map(int(N1),eta=eta0..eta2)

E2:=map(int(N2),eat=eat0..eta2)

E3:=map(int(N3),eta=eta0..eta2)

N1, N2, and N3 are 3x3 matrix are are functions of eta0, eta2. eta0 and eta2 are derived after several integration as well.

If i do not want to change the name "eta0" and "eta2", can i write something to indicate (eta0 for E1 is 8.3, eta0 for E2 is 4.5, eta0 for E3 is 7.9). I hope...

I am planning to use the "schedual task" in windows to try to launch
maple in the background (run under some different user account)
to do some computations.

For this pupose I have designed a little counter that is located in the
Start up code region:

for i from 0 to 100 do
if DataTable1(1, 1)=i then DataTable1(1,1):=i+1:  break; end if:
end do:

the DataTale will tell me how many times the worksheet has been opened
just to check...

Dear Maple users

The formula f = c/λ is expressing the frequency in terms of the velocity of light  c and the wavelength λ. Lets say given not just one wavelength, but a whole list af wavelengths. The values have units attached. I wonder if there is an elegant way to have Maple calculate the all the frequencies, eventually delivering them in a new list?

I want the units of the output reduced to SI-units,...

A simple question. I have this:

k*(2x+y-3z+2)+s*(5x+5y-4z+3)=0

And I want to group it by x, y, z, so that I would get:

x*(2k+5s)+y(k+5s)...=0

I'm using Maple 11.

Hello,

For a face recognition program I need to import all the jpg files that are in a map
on the hard drive. I can already do this by f(i):=Read("C:xxx\\xx\\xxx\\xxx.jpg"); 
that gives f(i) a single jpg file.
But this requires every file to be imported separately. Is there a way to import all the jpg
files from that map?
e.g. f:=Read("...\\*.jpg"); that would give f a list of all the jpg files in the map.

I am going to use maple in connection with my project concerning non-linear dynamic and chaos, but i have never used the program before, so I hope you guys can help me with that,

I have a model of non-linear dynamic system as following:

dA/dr = k + m * Y(r) - A(r) * B(r) * B(r) - A(r)

dB/dr=1/q * [A(r) * B(r) * B(r) + A(r) - B(r)]

dY/dr=1/s * [B(r) - Y(r)] 

the values of the parameters are:
k= 10
q= 5 * 10^(-3)
s=2 * 10^(-2)

Can I make a jpeg file into the background of a plot?  

I want to make a topological map the background of the xy plane.

Thank you.

To answer this question you need to create a Maple function using Maple's arrow (->) notation.

Your function should take a Maple list of real numbers as its input and return the smallest cosine from that list.

Enter your function in the box below.

Your Answer: op(1,sort(map(cos,x)))

Can anyone tell me how my answer is incorrect, or more importantly, what the correct answer is?

I need to install Maple 8 for the Mac OS. Would you let me know where to obtain it? Thank you very much!

I'm looking for a quick way, preferrably without using any loops to 'map' a function using several vectors.

In the single vector case, this is quite easy, but with multiple vectors, I'm not sure if map is the correct command to use.

For example:

u:=<1,1,1>;
v:=<2,3,4>;

f:=(x,y)->ln(x-y);

What I'd like to do is create a new vector from the map of the function onto both vectors,...

I find the singularities of an expression by using the function singular and the result of this is what I call t1a below.

Ive tried this for hours and can't get it to work. Any help would be greatly appreciated. I need to 

find a 10 significant figure approximation to the 10^th derivative of

Ive tried using this maple command:

Hi there,

I was woundering if there is a function implemented in Maple11, where I can enter a function and it's domain, and the output is the range. For example:

Entering f(x)=x^2, and the Domain x in (-1,2), I would want Maple to tell me that f(x) is in [0,4).

Is there such a function implemented? I need this quite often, most times on functions from R->R, but also more general for functions from R^n -> R^m. I know that in some cases you could...

Hello people, I have a question about an equation, I have to solve on maple.

So i have

>p:=a+bx+cx^2+dx^3;

>I1:=int(p(x),x=0..1);

>I2:=int(x*p(x),x=0..1);

>I3:int(x^2*p(x),x=0..1);

>I4:int(x^3p(x),x=0..1);

and i have to find a,b,c and d

the only thing i know is that I1=1, I2=0, I3=0,I4=0

can someone can help me. Thank you

I am interested in finding the asymptofic constant (Big O(1/n^(2m+2)) for the following expansion

Upon using the preceding command in the maple i get
