Dear Maple users

The Statistics package contain a Histogram command which can produce a linegraph (or what you call it). Ex:

with(Statistics):

A:=[3,5,7,2,11,2,1,10,6,15]:

Histogram(A,discrete)

It will calculate the frequency of each of the outcomes as they appear in the list and will plot them accordingly: 

How to prove that 

sum(binomial(n, r)*binomial(k+r, n), r = 0 .. n) = sum(binomial(n, r)*binomial(k, r)*2^r, r = 0 .. n)?

Maple calculates the LHS and RHS, but I cannot compare these with Maple for each n::posint and each k::posint s. t. k>= n. The question was asked in Mathematics SE. I don't understand whether it is answered there.

I am trying to see if Maple can help me find a closed form for an infinite series. I do this:

restart:

s:=Sum(n^2/((Pi^2*n^2+beta^2*epsilon^2)*(exp(n))^4), n = 1 .. infinity);

value(s);

Maple returns with:

Find a(n) of sequence 1 , 2 , 2 , 3 , 6 , 5 , 30 , 11 ,...

Dear sir, 

 i want to plot labelled contour plot in maple 13, 

here is the code

labelledcontourplot(x^3-y^2,x=-3..3,y=-3..2,axes=boxed);

thanks 

Hello everyone,

restart:with(PDEtools):with(plots):

sys := {diff(T(x, t), t) = diff(T(x, t), x, x)+(diff(u(x, t), x))^2, diff(u(x, t), t) = diff(u(x, t), x, x)};

PDE:={diff(u(x,t),t)=diff(u(x,t),x$2),diff(T(x, t), t) = diff(T2(x,t), x)+(diff(u(x, t), x))^2,diff(T(x, t), x)=T2(x,t)};

BCs := {u(0,t)=sin(t), u(10,t)=0,T(0,t)=1, T(10,t)=0,u(x,0)=0,T(x,0)=0};

pds2 := pdsolve(PDE, BCs, numeric, spacestep=1/50);

I just want to plot T2(x,t) vs t for x=0.

Sorry to bother you again. I want my computations(results) to carry/have more decimal places so that I can choose how many decimal places to show myself. This is because, my result is always displayed in 9 d.p but I want more decimal places to be displayed. Just like the way we change the way maple display matrix in-line with command interface(rtablesize= N), is there a similar way i can do the decimal place thing?

Secondly, how can i suppress the value A amd B from...

Help please...

How can I solve for

Congratulations to Christian Bär, a professor at the University of Potsdam, for winning the first individual prize of The Möbius App Challenge! Christian will be receiving a MacBook Air for his app The Cosmic Travel Planner.

Maplesoft launched the Möbius App Challenge earlier this year to give Maplesoft community members the opportunity to get involved in the creation of Möbius Apps. This contest seeks to challenge users to create Math Apps using Maple, submit them to The Möbius Project website, then award the most useful, creative, and effective submissions. Finalists from the individual level challenge are chosen four times a year, so make sure to enter the next round of the challenge for your chance at a Maplesoft prize pack!

I'm making a student quiz and would like to use Maple to enter long division problems. Is there an expression template in the palettes for entering long division?

Thank you.

I have a 3D data-points of the form x,y,z. What is the easiest way to get the interpolated value z=

I would like to use Maple to expand the polynomial (1+x[1]+y[1])*(1-x[1])*(1-y[1])*(1+x[2]+y[2])*(1-x[2])*(1-y[2])*(1+x[3]+y[3])*(1-x[3])*(1-y[3])*(1+x[4]+y[4])*(1-x[4])*(1-y[4]). This is dreadfully complicated, but things are simplified by the fact that (in my situation) each x[i] and y[i] disappears when squared (x[i]^2 = y[i]^2 = 0 for all i). Is there a way to make Maple factor this into the computation?

Cheers,

hi

I have a program with system of equations in wich my equations are in 8 matrices (4x4) with 64unknown parameters

i have run it but after 10 minitutes maple gives this massage:

"length of output exceeds limit of 1000000"

is there any way to solve this problem?

Hello

I am trying to solve an equation for optimization purpose, However I always recieve the message below:

Warning, solutions may have been lost

The Maple code is as follow:

PTE2.mw

I would be thankful if anyone can help me to solve this problem.

Cheers

Here is a solve problem based on theoritical analytic approach, http://math.stackexchange.com/q/460365/8581. May I ask make me hints in which I can visualze the region f maps. In the question we are speaking about $f(E)$, so I am thinking about a plot illustaring $f(E)$. Thanks for the time and any hints.
