In the attached worksheet there are 2 numbers. The first is the answer a got, the second is the offical correct answer.Ther look entirely different. Numerically they are the same. I wondering is there a way to simplify my answer?Rationalize_ans.mw 

The general formula of GHR (Gazis-Herman-Rothery), the most well known car following model, is given by

an - acceleration of vehicle n implemented at time t
v - speed of follower vehicle

Hello,

I have currently trouble running existing C-code in a new Linux (64 bit) system with Maple16. I have code that used work just fine, now it fails to evaluate. As an example, statements like

EvalMapleStatement(kv,"1+1+2^3;");

still work as expected and return a number. However, code like

EvalMapleStatement(kv,"int(x, x=0..1);");

returns int(x, x=0..1), i.e. a string, which causes my program to crash, because a number is expected.

Hi,

     So I'm having a little trouble with command-line Maple 16 on Ubuntu 12.04, 64-bit.  I can enter the commands

plotsetup(gif, plotoutput="testing.gif");
plot3d(sin(x)*exp(y), x=0..5,y =0..5):

and a .gif file will be created with the graph. However, if I save this as a text file "testing.txt" and run it via the terminal command

maple testing.txt

it does not save the graph. Any idea why this is?

So far I've tried

Hello,

Please when i solve a list of equation with fsolve i get a list of result:

How to copy maple output equation in word such that in word 2003  we can edit the equation

A1:=(-exp(-alpha*x))/(2*eta^3);

thanks 

I am trying to solve a three-point BVP, but Maple returns the error:

Error, (in dsolve/numeric/process_input) boundary conditions specified at too many points: {0, 100, 150}, can only solve two-point boundary value problems

Is Maple just not able to solve 3-point BVP's or is there another way?

Hy, 

I'm trying to display a list value in a maplet. But I can only manage to get textboxes, checkboxes and textfields. I know that in textfields I can display the evaluation of a function, but I tried many different ways and I still don't get the desired result. 

I designed a maplet with a button and 6 rows with a checkbox at the end of each row. When clicking the button I would like that the values of a list ("lstx", 6 values) are displayed in the 6 rows. Can you help me? thanx!!

I want to plot a graph of different values of k=0.1,k=0.5, k=-0.1, the display should be like this

my codes are 

restart:

V := exp(-x)*y^3/eta^3:

eta:=1+k*x+sin(2*Pi*x):

x:=0.1:

k:=0.1:

p2:=plot(V, y = 0 ..eta):

tf:=plottools:-transform((x,y)->[y,x]):

tf(p2):

plots:-display(tf(p2),labels=["v","y"]);

I wanna solve a collection of linear systems Ax=b_i, i=1..n, with A an upper triangle matrix, parallelly with Maple. Is there anyone can give me some suggestions? Thanks lot.

In this article I want to discuss the right way to store and build Maple code.

As mentioned in the Introducing the Maple IDE post, over 90 percent of the algorithms built into Maple are implemented using Maple language. The code of the algorithms is stored as Maple Libraries (.mla files).

As

would like to draw the pdf, however after tried two methods, still can not draw it,

how to draw?

 

l := [binomial(349,20), binomial(349,8),binomial(349,22),binomial(349,38),binomial(349,49),binomial(349,36),

binomial(349,59),binomial(349,41),binomial(349,32),binomial(349,21),binomial(349,23)];

sl := gfun[listtoseries](l, x, egf);

g := convert(sl, ratpoly);

g := g - subs(x=0, g); 

i invent a method to make use of gfun 

 

as i know series are the number of ways 

however, after i input the number of balls in each box

calculate into binomial and input into gfun, and plot the graph, the problem is value too big 

cannot plot 

however, if using the count directly as input, the graph can be ploted, however, this is not

the logic of my understanding

if input series are not binomial, what are they?
