{{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

even if I use a simple x^2+y^2 plot I get these funny gaps at the botom of the plot. I have looked through the FAQ files and can't seem to find a solution to it... is there one ?? from what I have seen so far there does not seem to be an easy solution. with a graph like the type above to change to coords=spherical or cylindrical does not show the same graph due to that change.

Hi,

I tried to implement an small example sheet for using the RSA algorithmen with small numbers. Unfortunatly, I get confused by my own program and have difficulties to figure out what I am doing wrong. My message can be decoded with both keys, the public and private key what is obviously not correct.

below is my code with some comments:

restart: with (numtheory):
p := 13; # my first prime number
q := 23; # my second one

n := p*q;

I am of interest about using StateSpace(de, invars

Hi all,

How can I plot, say, y1=x+4, 0<x<5 and y2=2x+1, 0<x<10 on the same plot area?

Thank you,

Ozgur

This is my situation, please help me.

Maple is such a useful and wonderful sorftware, but,

coud you make the classic worksheet compatible with 64bits?

There are packages (grtensor) that do not run on the new worksheet.
