Hello, I'm currently trying to solve this set of ODE's, but the way I have formulated the problem seems to be hard to process. Is there any simpler way of doing this, because it takes Maple a few minutes to solve 10 steps and I need more than a 100.Thank you in advance!l := 1.34*.75;Omega[p] := sqrt(g/l);v := .75;f[p] := .35*v^3-1.59*v^2+2.93*v;bmin := 0.157e-1;ci0 := y1(0) = 0, (D(y1))(0) = v;u0 := 0+v/Omega[p]+(-1)^0*bmin;p1 := diff(y1(t), t, t)+Omega[p]^2*(u0-y1(t)) = 0;k[1...

I know this has to be an easy on, but I simply cannot figure out how to calculate the probability of a dice roll or a card pick. I want to calculate the probability of rolling four sixes in a row, or picking three kings in a pack of playing cards. I know how to to the math by hand, but I want maple to calculate it for me. 
I've tried google my problem, but with no useful results (they were all a lot more advanced then what I could figure out). I'm guessing it's because...

Dear All,

I am a bigginer of Maple. I'm trying to solve the following in Maple.

 

> with(Statistics);
> f := Distribution(NormalDistribution(0.3,1));

> Y := RandomVariable(f);
> fy := PDF(Y, y);

> Fy := CDF(Y, y);

> int((diff(-ln(1-Fy), y))*fy, y = -infinity .. infinity);

> w := evalf(%);

 

But Maple told me that the answer is the integral -float(∞)..float(∞).

Hi,

I wonder if you could help me. I'm trying to calculate the eigenvalues of a complicated 3x3 matrix in Maple, but I'm not very familiar with Maple syntax. The answer maple has provided me with is in the form,

(&*(sin(pi*q/P),P/T,3x3 matrix))

How do I interpret this result? The eigenvalues are scalars.

Thanks for your help,

Sian

 

 

How can i use previous inputs in new maplet window.For example i have two maplet windows; maplet1 and maplet2 I use some inputs as a functions in maplet1 and i open new window by using botton from maple1.I also want to use same inputs for calculating function in maplet2

I have a set of sets named T. How I can take all possible unions of the members of T and if the result is not in T already, include it in T. I want to do this using a seq command, but could not do. Can anyone help? This is so to say, T is to be made closed under union.

how can i preform this calculation in maple?

(∂)/(∂ log(R[e[0]]))(log(N[u]))

it's a derivative of a logarithmic expression with respect to another logarithmic expression, the one on the bottom is a "standalone" vairable and the one on the top is a function of the previous one and some others.

thaks in advance to anybody who might help.

Hello!

I am having trouble comparing elements from to list, each having ordered pair as elements. 

What I would like to do is this:

 

if the first component of any ordered pair of the first list is equal to any from the second, then I would like the sum of their respective second components.

 

I am new in Maple, but I have already managed to create the lists I need...

  

 

 

I am using Maple 15 and when i use blew code , my system freeze!

 

n:=readstat("Input n:");
A:=matrix(n,n,0);
for i from 1 to n do
for j from 1 to n do
A[i,j]:=readstat("value = ");
od;
od;

where i have mistake?! is there any way to get an arbitrary Matrix with double for Loop? please help me! 

Hi,

I am using Maple 15 on a school server. In most of the times, the following screen occurs:

Can I get rid of that notice? My results got disappear very quickly to the TOP.

Is that something I can change or it has to be done from the admin?

And just a general question, do Maple run more or less faster on Linux/Unix machine than windows?

Hello,
I am currently conducting a study on the bridges and I need to solve a partial differential equations. However, despite all my efforts

hi, i have solved my equations with dslove numeric,with 3 terms approximations,it takes maybe 5 minutes to solve it,when i increase 3 terms to 4,it takes more than a day to solve,however my queation is about another problem,
i solved my equations with 3 terms approximation (in 5 minutes),when i want to get answers , for the very little times (i,g=0.00001) it answer quickly,but now i am calculating it for  t=1 seconds and it takes more than 12 hours to answer and it...

Hi all,

For research purposes, I have symbolic matrices of dimentions up to 100 x 50 (and above) with certain number of parameters. Then giving random value to those paramters, I want the numerical rank of the matrices.

 

Maple 17 does not seem to work well with symbolic ranks, where expentials are involved.

And more to it, both

Student[MultivariateCalculus][Jacobian]

and

VectorCalculus[Jacobian]

does not seem to work. ...
