Hello everyone,

I have owned Maple since I began post-secondary in 2010 and have not used it until recently.

What is the easiest way to calculate problems involving random variables?

For example, if is a Binomial(10,0.5) random variable, what is the probability that X = 3?

I found tutorials, but these used graphs, and all I want is a short and sweet way to identify the type of random...

I'm using maple 14 on a win7 2.8gHz 4gb laptop and over the past 2 days my maple has fallen appart, i'm trying to print a worksheet that is only 5 pages and not especialy complicated but maple's memeroy usage is exploding up to 400mb, or 1.3gb if i actually run the code. I need to print the work sheet and it just spent half an hour "spooling" i don't know what is causing maple to go haywire

hi frndz...i want to generate a matrix of order n x n in maple through loops..for example if equation is 
rUi-1,j+1 -2rUi,j+1 +rUi+1,j+1 = rUi-1,j -2rUi,j +rUi+1,j

then how to write code that it generates n x n matrix for above equation if at jth level values are known and j+1 level vaules are unknown...

Hi,

After upgrading to Maple 16.02, the Maple code:

eqn3:=diff(y(x),x)=x+sin(y(x));
IC3:=[y(0)=2,y(3)=0];
DEplot(eqn3,[y(x)],x=-5..5,IC3,y=-5..5,arrows=comet,linecolor=BLACK);

produces the directions field but fails to produce the solution curves.

I have tried the same code on two different machines running Maple 16.02 with identical results.  I have also tried the code on Maple 16.01.  In this case the solution curves are produced.

We have 12 sets S[1], S[2], ..., S[12] and the listlist LL:=[[2, 4, 5, 8, 10], [1, 3, 6, 7, 11], [2, 5, 6, 9, 10],
 [1, 5, 6, 9, 11], [1, 3, 4, 7, 12], [2, 3, 4, 8, 12], [2, 5, 10, 11, 12], [1, 6, 10, 11, 12], [3, 4, 10, 11, 12], [1, 3, 7, 8, 9], [2, 4, 7, 8, 9], [5, 6, 7, 8, 9]] which means that the set S[1] does not intersect with the sets
S[2], S[4], S[5], S[8], and S[10] (PS. but S[1] intersects with S[1], S[3], S[6], S[7], S[9], S[11], S[12]) and so on. What...

How to find the integral
int((ln(sin(x)^2+1)-ln(cos(x)^2+1))/(-cos(2*x)), x = 0 .. (1/2)*Pi)
in closed form with Maple?

Some plotting options only allow view option.  Is there another way to specify axes ranges?

In a BubblePlot, I want to display only a portion of the graph.  view works fine for single graphs no problem, but when I combine it in display with multiple graphs I don't want the unviewed portions in Bubbleplot re-appearing.  

for example

with(Statistics):
with(plots):
a := BubblePlot([4, 5, 2, 3], [1, 2, 7, 8], [8, 1, 3, 2],view=[default,4..9])

restart;
eta:=10^(-2.623+(3388.8/(T-491))):
DG:=51749.47800-33.65211624*T-0.4480891609E-2*T^2:
N:=((T/eta)*(exp(108.3606-(3.02397E13/(T*(DG^2)))))):
B:=(1.5438E-6*A*(1307-A))/(10^(-2.623+3388.8/(A-491)))*(1-exp(-abs(51749.478-33.6521*A-0.0044809*A^2)/(8.31*A))):
G:=int(B,A=500..T):
H:=G^3:
J:=N*H:
q:=evalf(int(J,T=500..1307)):
Rcc:=evalf((((4*Pi/3)*q)/1E-6)^(1/4));

hi all;

my orginal function is :

f(x)=(29/2)*x^2-(899/24)*x^4+(26941/720)*x^6+...

i want plot pade approximation and orginal function in the maple 14, i wrote command as follows:

is my command  Correct?    

> with(numapprox);
> f := (29/2)*x^2-(899/24)*x^4+(26941/720)*x^6;
> e := pade(f, x, [5, 4]);
> with(plots);
> P := plot(f, x = 0 .. 1, style = point, color = "SteelBlue");

Why does Maple put space after a new string?

How to prevent Maple from doing that?

A plot command with the only argument of

used to work (up through version 15).  With 16.02 Maple produces nothing but axes.  It is still smart enough to use its default range for the x-axix and to figure out an appropriate range for the y-axis, but it cannot (will not) draw the curve.

If I were a student wanting to...

hi,

I am trying to make a custom on maple but when i get an error on dynamicSystems saying:

> sys := DynamicSystems[AlgEquation](eq, inputvariable = [Altura(t)], outputvariable = [Teste(t)]);
Error, (in DynamicSystems:-AlgEquation) algebraic equations cannot depend on past/future values of the input/output

But if i change AlgEquation to diffEquation i get no error. I dont have any diff equation on the system. This is happening with one of the "equations":

Hello Everybody!
I am working on an interesting problem right now. Please read it and let me know what you think.

Lets assume there is some function f(v) where v is argument-vector with fixed length. It is known, that the function is a rational type of function with integer coefficients from the vector v.

It is required to find analytic expression for this function.

In other words, we can compute...

hi guys,

I'm working on a project for school that involves te mechanics of billiards; I've derived some equations using mechanics but a part of my project requires me to simulate a simple situation of eg; a collision between 2 equally sized billiard balls, assuming that they are treated as particles and that there is no friction,but there is a coeffecient of restitution to be determined.

If anyone could even push me in the right...

hi, i have a function in Infinite seri's with one unknown parameter and i want to solve it.
I use pade approximation in the MAPLE 15.
is it true!?
this is my function :

f(x)=(29/2)*x^2-(899/24)*x^4+(26941/720)*x^6+...

written in maple:

> f := (29/2)*x^2-(899/24)*x^4+(26941/720)*x^6;
> with(numapprox); pade(f, x, [5, 4]);

please help me

thank you
