The maplecloud may in some respects reduce the sharing of applications on mapleprimes and at the maplesoft application center.  A maplecloud user may instead of sharing his application via mapleprimes applications or the maplesoft website may just make his worksheet publicly available over the cloud simply because it's easier to do. 

It is true that mapleprimes is a different type of serviece that allows the interaction of ideas/questions as well as the sharing...

The result of "1/3 mod 7" is "5",how to understand it?What's the syntactic rule behind it?

Why isn't DEplot working when my syntax is correct? The equation will plot in one worksheet but not in another?

How do you find the intersection of 2 subspaces of R4

v1= [x(1,2,3,4)+y(0,2,3,2)]

v2= [x(3,2,1,1)+y(3,1,1,3)+z(6,4,2,2)

Hi all,

I need to:

a) Find the equation of the sphere passing through the 4 points [- 8, 3, 11], [5, - 7, 1], [- 15, 4, - 6], [10, 2, 9].  Give the coordinates of its center and its radius.

b) Plot together the sphere of part a along with the 4 points of the dataset.

I can't seem to get maple to do this!  I am very frustrated as the sphere command doesn't even seem to work.  I am a total maple n00b...

There is a problem which I feeling very puzzling, it is not the codes, but about when running the codes. It seems that if I running the codes immediately (or use "run all the worksheet" ), an error returned unexpectedly, but if I wait a few seconds before rerunning the code which just causes the error, a correct result returned. I feel very...

When I am trying to write the data of the following program in a datafile

restart

with(plots)

eq := (diff(G(eta), `$`(eta, 2)))/Pr-2*n*b*eta*G(eta)+(a+(1/2)*b*eta*eta)*(diff(G(eta), eta))

> A := {x=0, y=0}:

> B := {x=0, -y=0};

> {A} union {B};

{{x=0, y=0},{x=0, -y=0}}

How to get Maple to realise that A and B are actually the same so that "{A} union {B}" would return "{{x=0, y=0}}" instead of above?

Thanks in advance.

Mapleprimes takes unusually longer to load than used to.  And some people complain about being emailed 3 x's I'm not sure it's fixed but I've noticed my page actually loading 3 times before it actually comes up.  I'm on dial up so I can notice things people on high speed won't notice.

One other thing possibly very important to the web program designers of this site.  If I load the mapleprimes web page and say stay offline, it does this 3 times. ...

 It seems I can't add a response to this message, so I added some detail to it.

How to join expressions in the set, for example to convert the set {y=0, x>-1, x<1} to {y=0, -1< x <1}?

Thank you in advance.

Hi all,

when drawing a geometry.line object by using geometry.draw, the default for each axis is -10..10, so that I cannot see in the plot, for example, the line y=11;

How can I extend this range?

Best regards

I want to plot a bunch of straight lines with positive slope in one colour, and I want to plot a single line of negative slope in another colour.

I hope my code is self-explanatory:

restart; with (plots):
myEqns:=NULL:
for i from 1 to 5 do;
 myEqns:=myEqns,y-x=i;
od:
myEqns:=[myEqns];
 [y - x = 1, y - x = 2, y - x = 3, y - x = 4, y - x = 5]
implicitplot([op(myEqns), y+x=0], x=-10..10, y=-10..10, colour=[red,blue]); 

I'm trying to have Maple work through ideas involving the Fundamental Theorem of Calculus, and am encountering a problem with the programming of Maple.

I begin by defining a function like:

F(x) := int(x^2,x)  (or equivalently, F:= x -> int(x^2,x)  )

Then I ask Maple to evaluate F(2).  I expect to get 8/3 but instead I get this error message:

Error, (in int) integration range or variable must be specified in the second argument, got 2
