So I am doing a project for my stat class and I'm using maple to generate the simulation of russian roulette. What I want to do is have X1 through Xn trials, and within each trial I would like to simulat a round of russian roulette where the round ends upon the gun firing. Then I want to take how many times the trigger was pulled in each trial and make a n by 1 matrix where the column is the amount of times the trigger was pulled in each round, and the rows being the specified...

I want to simplify (x+1)/sqrt(2*x+2) into sqrt((x+1)/2). Is there a way to do this?

I like to use Maple as an informal  text editor for math correspondence. (I do not use Tex and am firmly committed to not learning Tex. Principled laziness.) I usually insert a Document block in a new worksheet, type my letter utilizing all the wonderful automatic formatting-powers, symbols, integrals, etc. easily available in Maple and then print the resulting document as a pdf and email it. It is much more readable for me and for the person receiving the document.

Is Maple able to get the lightning data from here www.lightningfinder.com

The map is refreshed every 30 seconds and displays where the lightning strikes are occuring.  I can't determine where the page is getting the data from.  Where is the page getting the data and how can we use Maple to pull the data? 

I understand completely how the Playfair cipher works but I'm not sure how to begin to implement it into Maple. Does anyone know how to begin encrypting and decryptin a code using this cipher?

Hello.

I took the battery out of my laptop by a mistake while it was in sleep mode. Now maple can't open the document even though i did save it before. It opens a file where 80% of my work is gone.

Download BET.mw

Maple says Incomplete worksheet when I open the file.  

Can someone please help me?

Hi all,

I am trying to get the following matrix:

restart:
int00:=Matrix(3,3);
int00[2,2]:=a;
int00[2,3]:=b;
int00[3,2]:=c;
int00[3,3]:=d;
int00;
cols:=MTM:-sum(int00,1);
rows:=MTM:-sum(int00,2);
int00[1,1..3]:=-cols:
int00[1..3,1]:=-rows:
int00;

int00[1,1]:=a+b+c+d:
int00;
MTM:-sum(int00,1);
MTM:-sum(int00,2);

How do I get the sum of all elemnets in the 'original' matrix? Bascially, the int00[1,1] term in the toy example.

Z := proc (theta) options operator, arrow; sin(theta+2.3)+sin(2*theta+2*(-1.5))+sin(3*theta+3*(-0.94e-1)) end proc

Zbar := proc (theta, phi) options operator, arrow; Z(theta+phi)-Z(theta)end proc

plot3d(int(signum(Zbar(theta, phi)+l)*abs(Zbar(theta, phi)+l)^(1/4), theta = 0 .. 2*Pi, phi = 0 .. 1, l = 0 .. 1)

I want to find all the max or min values in a range, from a numerical function [t,x(t)], numerical solution of a differential equation.

For example if the solution was periodic in time, I want to find the max values of x in a certain intervalot t

Hi Guys. I´ve got a problem with the mod (mods,modp) function of maple.

I want to calculate the following congruences:

mod(4,-5) = -1 BUT maple returns 4

mod(-3,-4)=-3 but maple returns 1

and so on....

Does anybody of you know how to fix this? thanks!

Hello,

I have a problem. I want to make plot 3d for pressure drop in diffuser by posuille formula,

The system consists of 3 equationsHow can you single out one of the solutions in obtaining module and plot for it?
a := 1; m := 1/64 
l1 := 2*(diff(ur(e, t), t))+(1+tanh((1/20)*e))*(diff(ui(e, t), `$`(e, 2)))+2*a*(ui(e, t)*ur(e, t)*ur(e, t)+(ui(e, t)*ui(e, t))*ui(e, t))+m*ui(e, t)*(diff(ur(e, t)^2, e))+m*ui(e, t)*(diff(ui(e, t)*ui(e, t), e)) = 0

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&...

When I solve a systems of equations, fsolve gives the solution

.

I now want want to define the variables x, y and z as respectively 5, 6 and 1 - but without copying the solution. Because this is a solution that I get in a loop, so it changes in every step. Maybe there is a easy way to put it in a vector?
