how to plot tail of normal distribution

would like to see the shape of tail of distribution

 Hi all,

i want to solve a system of differential equations in maple with "dsolve, numeric",

i got th error message: "Error, (in f) unable to store in Matrix ..."

what is the problem?

thanks a lot

Suppose (1 + 2x)^n = a0 + a1*x + a2*x^2+...+an*x^n.

I want to find value of n so that max(a0, a1, ..., an) is a8. 

I tried directly. 

With n = 12. 

restart:
A:=expand((1+2*x)^12,x);
max(coeffs(A));

And with n = 11. 

B:=expand((1+2*x)^11,x);
max(coeffs(B));

Therefore,  n = 12 or  n = 11. 

How can I solve the problem with Maple?

What is the command to get a sequence of the first twenty prime numbers

why system inconsistent 

when only want to obtain a equation H

in terms of a1 , a3, b2, b3, c1, c2, x1, x2, lambda

pdsolve([
Diff(H(x1,x2,lambda), x1) = a1*x1 + a3*lambda,
Diff(H(x1,x2,lambda), x2) = b2*x2 + b3*lambda,
Diff(H(x1,x2,lambda), lambda) = c1*x1 + c2*x2
], H(x1,x2,lambda));

Hi all. I am using Maple 18.

1. Does Maple only output an answer, or can it be made to display the steps it took to achieve the result, in a way that is logical and understandable by the user? For example, I would like to see it display steps when integrating or differentiating, or dividing a polynomial by another polynomial. Basically any process that involve simplifyinf or factorisation.

2. I am trying to divide x^2 + 5x + 9 by x+2, but all Maple displays is the expression

How can I make it do the polynomial division and output the steps it took? I tried using simplify and evaluate from the context menu but the output is still just the expression.

3. Has something happened to this site? It was working fine in Opera until two days ago, and has sinmce started displaying "Error generating page" where the replies to questions should be. No problems with the "posts" section, only in the "questions" section.

Thanks in advance.

Is there a document with all elementairy plottools commands to find?

i must construct a numberline and lines to e4xplain with a arrow and text under it.

with(Finance):
with(Statistics):
X:=RandomVariable(Binomial(nn, pp));
Drift(X);

How to listplot two vectors on the same graph?

That means having two lines.

f1 := -2*x1 - x2;
f2 := -x1 - 4*x2;
g1 := 2*x1 + 3*x2 - 6;
g2 := -x1;
g3 := -x2;
penalty := lambda1*Max(f1-M,0)+lambda2*Max(f2-M,0)+(M^2)*(max(g1,0) + max(g2,0) + max(g3,0));
M := 1;
k := 1;
s := 1;
lambda1 := 0.5;
lambda2 := 0.5;
with(Optimization):
Minimize(subs(lambda2=0.5, subs(lambda1=0.5, subs(M=1, penalty))));

correct answer for these parameters should be below, however, Minimize got error

when lambda1 = 0.5, lambda2 = 0.5
(x1, x2) = 1.551123, 0.965918
f(x1, x2) = (–4.068164, –5.414795);

I have some data for a model in MapleSim that I would like to use a time look up table with.  I've found that the two options for interpolation are linear and 1st derivative, but the data was intended to be interpretted as piecewise constant.  Is there any way to acheive this option in MapleSim?

Hi everybody,

I'm an mechanical enginer and I have to solve numerically this kind of differential equation : m(d2z/dt2)+c(dz/dt) + k*z = F where z is the displacement.
The best resolution for this problem is to use a Newmark method (which is available here at page 10 http://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&ved=0CEEQFjAE&url=http%3A%2F%2Fpole-modelisation.univ-bpclermont.fr%2Fcisssi%2Findex.php%3Foption%3Dcom_docman%26task%3Ddoc_download%26gid%3D110%26Itemid%3D51&ei=8seqU5-wEaS00wXm14G4CA&usg=AFQjCNFerFoQ4O-nrIdOoUiX7SIkLMb6sA&sig2=MZ6BxmUPm7Gg3CGcH4nknQ&bvm=bv.69620078,d.d2k)

So I have written this method in Maple but nothing happen and I don't where the mistakes are. So if somebody could help me, that will be great.

My code is :

Hi

I tried to import the modelica library Buildings1.6 from the modelica website and get always the error "Nothing found in the modelica library". 

Is it possible to import modelica libraries? 

Thank you very much

in maple 12 or 15

assume 

result := Vector(10);

for i from 1 to 10 do

        result[i] := i;

od;

how to plot it against i?

after tried plot(result(x), x=1..10);
