How to find the limit
limit(int(abs(sin(f(x))), x = 0 .. T)/T, T = infinity) assuming T::positive;
with Maple in the cases: a) f:=x->x^2; b) f:=x->x*exp(x)?

PS. Or to establish its nonexistence.

Hi all,

To share a maple document, I found this Maple help.

To share worksheet content:
1. In Maple, open the worksheet that contains the content you want to share.
2. If you want to share a worksheet selection, select the text and objects in the worksheet. If you want to share an entire worksheet, you do not need to select any text or objects in the worksheet.
3. Expand the MapleCloud palette.
4. From the drop-down list in the palette, select...

On the topic of the quality of rendering of (2D) Math on websites, could that also be re-examined for both Mapleprimes and Maplesoft's on-line help system?

Right now the on-line help has pages with missing images in Examples. For example, the `int` and `sum` on-line help pages, here and here.

On that

Ive tried this for hours and can't get it to work. Any help would be greatly appreciated. I need to 

find a 10 significant figure approximation to the 10^th derivative of

evaluated at x = -2.

Ive tried using this maple command:

evalf(subs(x=-2,diff((sin((x^2...

Why do I get different results for these four command? BTW only Result #2 is correct.

> evalf((1/2)*sqrt(3.0), 5);
                            0.86605
> evalf((1/1)*sqrt(3.0*(1/4)), 5);
                            0.86603
> evalf((1/1)*sqrt(3/4), 5);
                            0.86605

> evalf((1/2)*sqrt(3), 5);
                            0.86605

I have read the answer to a similar question, 

Hi,

I have this dataset of 3d points. It looks like [[x, y, z], [[x, y, z] ... [x, y, z]]. The y values represent days and can occur multiple times.

I would like to plot a surface from the data. I can plot the curves representing each of the different day values. It looks like the one below (might not be the most elegant solution ;-)). I would like to connect the curves with a surface. I have already looked at listplot3d without luck.

Thank you.

Hi

I would like maple to provide the coefficients of the derivatives of a PDE. For example:

Given PDE: 2Uxx+6Uxy+3Ux+2U=0

 Provide the coefficients of: Uxx Uxy Uyy Ux Uy U

I would like to get something like: 2 6 0 3 0 2

I tried "dcoeff" and "collect", but they don't seem to work for me

Thanks!

Hello,

I want to randomly generate variables and numbers that look something along the lines of this:

(3x)(-2y²₎
(-3x²y⁴) (4x²)
(-b²y⁴) (2b²)
(-3x²y⁴) (4x²y⁴)
(4x)(5x²₎



Here's my code so far:

for k to 5 do

V := LinearAlgebra:-RandomVector(2, generator = rand(1 .. 9));

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...
