Occassionally when I simplify maple puts a negative sign out front.  How do I get maple to put it back in the equation?

Something like (3+4i)/(-3+7i)  When I simplify maple shows   -  (3+4i) / (-7i+3) 

I'm really not sure why maple would factor out a (-1).   In any case how do I reverse it?

hi

i am doing a multiple integal integration from one of my tutorial sheet

 

Given D is the triangular region whose vertices are (0, 0), (Pi,0), (Pi,Pi), find

Int(Int(x*cos(x+y),x),y);

 

then I worked out something like

 

Hi,

I'm trying to obtain data points in an array or list form

from the plot I've drawn from implicit plot function.

Can anyone help  me?

Your help will be greatly appreciated.

Hello everyone,

There is a problem that I cannot solve (I just learnt Maple's language one day ago and I'm not a programmer):

I wrote a procedure which asks the user to enter any number of (x,y)  pairs and then calculate some polynomials between x_i and x_(i+1) for  i=1..nargs/2-1.

Then I want to combine these pieces of polynomials as a  piecewise defined function. Can anyone tell me how I can do it? In 

hi,

 

i ve to animate a function with maple. but my animation "vanishes" after some time so i wonder what i did wrong

my function f (x,y,t) = sin(sqrt(x^2+y^2-t))/sqrt(x^2+y^2-1)

this is how i tried it:

f := (x,y,t)->(sin(sqrt(x^2+y^2-t))/(sqrt(x^2+y^2+1)));
plots:-animate(plot3d, [f(x,y,t), x=-10..10,y=-10..10], t=-100..190);
 

if you let the animation run the animation starts to vanish, what am i doing wrong

Is there a way for maple to display an answer with a set order?  or set it so it always does it a certain way.

As an example, lets take eq1:=a=(v-v_o)/t then solve(eq1,{v});  (I put the v in {} so the answer will display the full equation).  Without the {} it only displays the answer.  Anyways, the answer returned is {v=a*t+v_o} 

I would like to manipulate it so that maple will always display an equation with a single variable first.  So, for in our example I would like it shown as  v=v_o+a*t

Hello,

0^0;

1

0^x;

0

Anyway to tell maple not to reply 0 if x value is unknown ?

Hello,

I have made some code using lists. At some points maple answers with a memory error, telling me to "try using Array instead". Ok tried, and it works better (with some code rewrited, as Array argument values are not duplicated)

But searching in help/doc/forums for size limitations of maple objects i find nothing. Where can i find such informations ?

Basically if we have a:=x^2 and I subs(x=b/c,a) we get b^2/c^2. 

How do I get maple to display it as (b/c)^2?

Sometimes I do stupid things like: a := Generate(set(integer(range=1..999999999999), 1000000))); Because of the ";" the result is that Maple quickly generates the set but then locks up and spends about 10 minutes trying to display the contents. Clicking the "abort computation" button doesn't help after the result has been calculated. Is there any other way to get maple to abort in such a case? If not is there a way to stop it from displaying lists of more than say 10000 elements? PS.

Hi

In the programme I am writing, we need to multiply axb with "a" being an integer, but found as a product of 2 matrices, and "b" being a 3x1 matrix. Currently I receive the message "Error, (in rtable/Product) invalid arguements" with the following code, can anyone help?

Hello,

I have a problem with my coursework.

Here it is: how to generate a random data points (x_k,y_k) for k=1,2,3,...30

I know how to do  (more or less) the rest of the task but to generate this points no way!"!! Please anyone can help me???

Thanks

 

 

Hi all,
