In the Belgium lottery they pick 6 numbers out of 42   (  there can't be 2 equals numbers being picked out )
Now for my maple homework , i must do some exercices in maple

1 ) Simulate the lottery
2 ) If you partici

This is a continuation of the new thread that was started with this post.

Code to create a maplet that generates unique random numbers from a sample space could look like:

Hi,

I got something like:

t:=NULL:

for i to nops(S) do

...

...

temp2:=(temp)^(-1) mod t[i]:

...

...

od:

 

the problem is that since I have assigned t:=NULL

for i=1

there is a problem to run

temp2:=(temp)^(-1) mod t[i]:
 

it becomes

temp2:=(temp)^(-1) mod t[1]:

at that time 't' is actually a number , just a single value, so it cant have subscript.

 

how do I solve that problem?

 

Hi,

I am writing an procedure in which has the following:

print( array(  [['p', 'q' , 'e', 'd'],
          seq([p[k],q[k],e[k],d[k]],k=1..nops(M1) )       ]));

that 'p','q','e' and 'd' all have been used within the procedure.

The "print", in the first line     "['p', 'q' , 'e', 'd']" , I would like them to display as texts, how should do that?

Thanks.

Hi,

I can generate 1 random number  by

rand(10^20)():

how can i get, say 6 distinct random numbers in the scacle of 10^20 as well?

Thanks.

How do i print numbers upto 100 that are not multiples of x,y,z?
 

I would be very gratefull for any help
 

Thanks

I just want to reiterate how dynamic programming problems can be solved in Maple.

Especially dynamic programming models that frequently appears in economic models.

First of all it is important to note that is close to impossible to find an easy to understand

and step-by-step road maps to dynamic programming. Why is that ?!  The below Maple

code was basically "discovered" by trial and error and pure stubbornness (caveman 101).

 

Hi All,

I searched the forum and found labelledcontourplot that would give the values/label on the contour plot.  However, when searching the Maple 13 Help for "labbelledcontourplot", the search does not return any result.

 

Thanks fo ryour help.

 

How do I plot f(x,y) = x^3*y, constrained to x^2 + 2*y^2 = 8? 

Thank you for your help.

You can easily (or at least comparatively easy) create Maplets in Maple but you can not (as far as I know)

create shortcuts to such Maplets in the main menu. I must say I find this very strange.

It is like having the tools and resources to build a boat but you don't have access to water.

I don't want to create a Maplet and having to open a worksheets each time I want to load the Maplet.

It just destroys the whole experience. Again I find this very strange :-)

 

Let we have a function, f(x), and want to approximate its integral from x = a til x = b.

Divide the interval [a,b] into n equal (not necessary equal) parts.

Let one of the part, i,  is from x(i) til x(i+1).

Let us draw a tangent to the curve in this part, i, by the command:

Tangent(f(x), x=(x(i)+x(i+1))/2)

we may find the area under this tangent and in this interval through the command:

int(%,x=x(i)..x(i+1))

Thus in ths limit:

the original area is equal to the sum of these areas.

Hi,

I would like to work in modula 26 for the whole workshee.

 

What's the command for that?

 

Thanks.

How to find a pattern in:

 

1, 3, 240, 840, 80640, 887040,...

What is the pattern in these polynomials (how to generate them)?

 

1. x^0

2. 3*x^2 + 3* x + 1

3. 240*x^4 + 480*x^3 + 380*x^2 + 140*x + 23

4. 840*x^6+2520*x^5+3220*x^4+2240*x^3+903*x^2+203*x+22

5. 80640*x^8+322560*x^7+571200*x^6+584640*x^5+379008*x^4+159936*x^3+43272*x^2+6984*x+563

Hi! I have a problem and I don't know what is wrong. I have a piecewise defined function s(y) (see code at the bottom) and I want to integrate it from y=-Pi..2.338412729. I did this integration int(s,y=-evalf(Pi)..2.338412729); but it took so much time so I canceled it after half an hour! But if I enter the integral in the following way int(s,y=-evalf(Pi)..2); int(s,y=2..2.338412729); it takes Maple less than five seconds to evaluate those expressions. The problem is this whole integration process is integrated in a proc for optimization. So, I need to evaluate the expression
