assume i have a number 26 and assume a prime number not greater than a value, let it be 5

then it is like a division and factor into 5^2 + 1

if prime number set to 17, then it will output 17 + 3^2, 

the output will be in terms of prime number, such as  a^3+b^2 + c  where a and b are prime number

it should start from greatest prime number given as a parameter in function

Good morning,

my name is Agnieszka Dymek, I'm a Polish student and I have a question or request. I'm looking for a quite difficult, interesting problems to solve it on Maple. I need this for presentation on lecture, for my friends - it have to be exercies with application different, special function of Maple programme. I was looking for it on Polish websites and I didn't find anything interesting and complicated. 

If You have something in database or somewhere,...

I have a large sheet containing about three proc(). Four symbolic matrices of though small order but with complex values are being imported. There are also some other statements other than mentioned above. I have writing them in text mode.

What could be the possible reasons for connnection lost with maple though I have 4 GB of ram.

 

Thankyou!!!

Let say that you have two datasets:

restart:
with(MyFinance):
z1 := GetCSV("http://www.quandl.com/api/v1/datasets/USER_18Q/18R.csv?&auth_token=BXckVSG3twWkV272c9Q4&trim_start=1968-04-01&trim_end=2013-04-12&collapse=daily&transformation=rdiff&sort_order=desc");
z2 := GetCSV("http://www.quandl.com/api/v1/datasets/USER_18Q/1EV.csv?&auth_token=BXckVSG3twWkV272c9Q4&trim_start=1994-01-03&trim_end=2013-04-12&collapse=daily&...

I often have to create density plots with many (thousands of) points. Hence the first thing I do when I install a new version of maple on linux, is edit dir_of_maple/bin/maple so that

JAVAHEAP=512

is instead

JAVAHEAP=4096

I have done this for years and never have any memory problems. But recently I have sent my code to someone who runs Windows and they seem to have "out of memory" issues when trying to do density plots of large datasets.

 

Hello,

I am trying to modify Maple code so I have a vertical spring with a mass starting at (0,0). The spring with the mass should move right and left along x. My vertical spring move up instead of down while the mass move to the right .

Any Idea about how I can get the right movement of the spring?

 

Please ignore the equation eq since I am only trying to have an animation spring with a mass.

 Thank you

 

"Welch-Satterthwaite formula":
With the package "ScientificErrorAnalysis" is easily calculated, the combined uncertainty of a mathematical model M = f (x1, x1, .. xn). But if I need to know the components of the calculation model uncertainty becomes very repetitive. For example to calculate the expanded uncertainty should be calculated uncertainty components model for using the Welch-Satterthwaite formula ". Which determines the effective degrees of freedom υeff:

Determine if

[ 9 ]                         { [ 3 ]  [ 1 ]  [ 4 ]  [ 1 ] [ 5 ] }

[ 8 ]                         { [ 2 ]  [ 6 ]  [ 5 ]  [ 3 ] [ 5 ] }

[ 3 ] E (curvy E) span  { [ 9 ], [ 7 ], [ 9 ], [ 3 ],[ 2 ] }

I have the following problem with the commands "Infinitesimals" and "InvariantSolutions". After using them to a system of firsst-order PDE's, the following message appears:

 

 Error, (in table["k"]) expected a request of prolongation w.r.t one of 2 independent variables; received a request w.r.t the (inexistent) 4th one

Does anybody know, what this message means ? I am a beginner with the commands "Infinitesimals" and "InvariantSolutions"...

Good afternoon everbody,

I am trying to make a rational interpolation from the data of a function (values of the function for different points).
I tried to do it with the RationalInterpolation command but it requires too much time. Then I chose to solve the problem with the NonlinearFit command but the result varies a lot if I a change the basic function I want to approach and I always get a warning message: limiting numer of iterations reached.

 d^2(x)/d(t^2) + sin(x)=0  (1)

d^2(x)/d(t^2) + x = 0 (2)

d^2(x)/d(t^2) + ( x - (x)^3/6) = 0 (3)

1) Compare the results of numerical simulations of (1), (2), (3) to see how closely the period of the periodic orbits relate.

a) Perform a phase portrait ( (x)'(t) vs. x ) analysis for (1), (2), and (3).

b) Consider the initial conditions x(0)= x0 and x'(0)=0. For what intervals of x0 do the periodic orbits of (2...

Hi everybody. Firstly, i apologize for my poor level of english. I am a new maple user and i want to solve the following system, but I face some difficulties. I go through forum, FAQ, courses notes on the net and so on but I don't find the solution. 

I first define the folowing equations:

 

I was working with the computation of the eigenvectors of a 3X3 symmetric matrix with algebraic entries and Maple 17 doesn´t give me an answer after a long time, even with CUDA activated. You can see this by the commands below:

above link's comment said eliminate will NOT generate a polynomial in all cases

make me think that eliminate in above link can not return correct one.

what is the correct way to convert groebner basis of kernel into kernel?

I sometimes like to work with worksheets in classic mode. However, I have just discovered that I cannot simply type "restart;" in the beginning of a worksheet in classic mode because it causes the worksheet window to freeze. However, if I click the "restart" button, then things go as normal. I really want to have each of my worksheets begin with the "restart;"  command. Need your assistant on a way out.

I use 64-bit windows 7 CORE i3 Dell Inspiron N4050.
