Several months ago, I'd posted a two-letter-words quiz and a two-to-make-three quiz meant for fans of the Scrabble game. Here is a third worksheet that tests your ability to find anagrams of seven-letter words. The worksheet is structured around six-letter stems and the lists of seven-letter...

Hello,

I want to pick 3 random(ish) points from a 3D plot for using in an iterative scheme. 

Is there a way of doing this by just clicking the plot and getting the (x,y,z) values for the specific point or is it something more complicated?

Thanks,

Rachael

We have a set S of 30 elements and choose its subsets A, B, and C such that nops(A union B) = 5,  

nops(A intersect B intersect C) = 3. How many ways are there to produce that?

How to count this number  with Maple?

Maple IDE team is launching a Tester Program that will allow us to incorporate more input in the product design and development process.

We are looking for regular testers for Maple IDE. Your testing complements our in-team testing of new software versions. By enlisting a diverse group of beta testers, we can see how the software performs when it's being used for normal, ordinary tasks. This lets us provide a more стабле Maple IDE with better user experience. As a member...

It is known that the trigonometric functions of an integer number of degrees may be expressed by radicals if the number of degrees is divisible by 3. Simple code finds all these values ​​in the range 0 to 90 degrees:

 [sin(`0`^`o`)=0,`   cos`(`0`^`o`)=1,`   tan`(`0`^`o`)=0,`   cot`(`0`^`o`)=infinity];

for n from 3 to 87 by 3 do

[sin(n^`o`)=convert(sin(n*Pi/180),radical...

Hi all,

I try many ways to solve the below DAEs, for example stiff=true, method = rkf45_dae, method=rosenbrock..., but my DAEs can't be solved. In different ways, there are different errors, such as "Warning, cannot evaluate the solution past the initial point, problem may be complex, initially singular or improperly set up", ""

Would you please show me how to solve the below DAEs and plot their solutions?

I really appreciate your help.

Hi!

I think I have quite simple problem, I can´t solve.

I have the following fraction:

and want to show it this way:

Multiplying the first fraction with (-1)/(-1) doesn´t work as expected.

Is there anyway to prevent Maple from converting a log10 function to a ln function when it displays a result?

Bonjour,

Qui peut m'éxpliquer l'algorithme de division d'un polynôme P(X,Y) sur un polynôme Q(x,y) ?

Avec mes plus vifs remmerciements,
Raymond Gérard.

after union ideal I and J, how to remove the intersection of I and J in order to do primedecomposition?

G1 := [v*y-w*x, r*y-u*x, -v*u+w*r, u*y^2-v*x^2, u^2*y-v*r*x, u*w*y-v^2*x, u^3-v*r^2, u^2*w-v^2*r, -v^3+u*w^2, x^4-r, x^3*y-u, x*y^3-v, y^4-w, w*y^2*x^2-v^2];

TypeTools[AddType](`w`,typefunc(string, symbol));
L:= `if`(G1::`w`, [op], '[]')(G1);

it seems above code incorrect.

Dear friends,

I wonder how I would go about calculating the asymptotic expansion of

sum(5^j/j, j=1..m+1)?

The motivation for this calculation can be found here. The correct answer is

5/4 5^(m+1)/(m+1).

The classic asympt and the one from multiseries both fail on this one.

Thanks,

i need your kind sggestions for this. i wrote the function w:=(xi(t),eta(t),diff(xi(t),t),diff(eta(t),t))→value.

but i cannot get the output, it wrote error in argument name. here value means the expression of the function.

best regards
