Dear all;

 

Hello everybody, I need your help to dispaly some values obtained using my function f. When I run the code there is no results obtained. Many thanks.

restart:

# The vectors e(i) satify the folowing conditions
e(0)*e(1)=e(n-1) assuming  1<n;
e(0)*e(0)=e(2):
e(1)*e(1)=e(n-1) assuming  1<n: :
e(2)*e(1)=e(n) assuming  1<n:
#
for i from 1  to n-1 do
e(i)*e(0)=e(i+1);
end do:

# We define the function f
f:=e(0)->e(0)+(n-3)*e(1);
f:=e(1)->(n-2)*e(1);
for i from 2  to 3 do
f:=e(i)->(n+i-3)*e(i)+(i-1)*(n-3)*e(n-3+i);
end do:

for i from 4 to n do
f:=e(i)->(n+i-3)*e(i)
end do:

# We define the two vectors
x:=sum(alpha(k)*e(k),k=0..n);
y:=sum(beta(k)*e(k),k=0..n);

#Question : I would like to compute the following  but there is no display of the solution. 
(x*y);
f(x*y);
f(x);
f(y);
x*f(y);
f(x)*y;
f(x*y)- f(x)*y-x*f(y);

I am interested in dynamic systems that changes system equations at a given point in time. So i often want to plot graphs that shows what would happen in the first 500 seconds, then using the point reached after 500 seconds as the starting point show what happens over the next 500 seconds.

For example my equations might innitially

diff(x,t)=x+p*y

diff(y,t)=x/y

and then after 500 seconds switch to 

diff(x,t)=x-p*y

diff(y,t)=x/y

simply estimating where the system is and feeding that into the other equation isn't an option because these equations have lots of parameters which p is representing in the above, and generally i want too use these graphs to illustrate the behaveious of the systems with the given parameters.

So far i use display and DEplot to make these grpahs.

Hi everybody,

Ever since i updated to maple 2015, the output of calculations display a disproportionate amount of zeros. For instance:

If i write:

2.3*10^(-4)

i get:

0.000230000000000

Is there anyway to make maple NOT display the last 10 zeros? I've tried Tools ->Options ->Precision -> Round screen display to X. But then it rounds all results to that X amount of digits, wich is also anoying. Like, if i set X to be 10, it'll write 3.000000000 instead of just 3.

Hope someone can help me :-)

The plot command outputs a graph of symbols where the line is made up of "H"s, vertical lines on the axes are "+"s, horizontal lines on the axes are "-"s, and intercepts are "*"s.

 

How do I fix this problem so that the graph displays a graph normally?

Hello everyone, I'm a new one to Maple, I've just learnt some basic tools.

I want to creat a command that can animate the graph of line y=ax+b by the parameter a, and b will be subscribe later. For example, I can plot y=x+b by:

F:=b->plot(x+b,x=-1..1):

display(F(1));

It did work.

However, applying this with animation didn't seem to work. 

F:=b->animate(plot,[a*x+b,x=-1..1],a=0..10,frames=5):

display(F(1));

It did not create an animation, instead 5 frames of this graph for a=0, 2.5, 5, 7.5, 10

Please show me a solution for this problem, thank you

 

I related two Text Area Components by using the codes "Do(%text_beta_radian=evalf(%text_beta_degress/180*Pi))".

I wanna know what codes can refresh the display of the text area component with name%text_beta_radian

after I change the input value of that%text_beta_degress?

hi all

i have tow plots and i want to display them together, but i cant, plz help me

restart;

I5:=Int((x^2)/((x^4-2*x0*x^2+x0^2+1)^(3/2)),x=0..infinity);
I6:=(1/2)*Int(1/(x^4-2*x0*x^2+x0^2+1)^(1/2),x=0..infinity);
f:=((-4/Pi)*((x0*I6-I5)/(x0*I5+I6)^(1/3)));
B:=x0/(x0*I5+I6)^(2/3): #B:=mu/eF
C:=B/((16/Pi^2)*((x0*I6-I5)^2/(x0*I5+I6)^(2/3))): #C:=mu/epsilon0/2

p1:=plot(B,x0=0..4):
p2:=plot(C,x0=-3..0):
display({p1,p2},x0=-3..4);

 

 Maple code when open saved maple sheet?

and keep it can run code and show latest result after open

i mean user can not extend or find code or display code in maple sheet , just can run result

Shading is not valid as an option in the command defining a plottools object e.g. a parallelepiped, and yet shading can be selected in the actual display of the object. Is there a way to code for shading when creating the object?

How can I display in Maple T.A. the content of a matrix as pure text?

Thus instead of

matrix([[1, 2], [3, 4]])

1 2

3 4

Is there a solution without using Mathml and hopefully without using StringTools?

And can I assign the rectangular text display to a variable (including line feeds)?

I wish to display the following screen output from a procedure A(), in a textbox of mathcontainer or any other suitable component.

 

This output to screen listing is generated by print statements in the procedure A().

I have placed the procedure call A() in a textbox and then am using a button component to execute it with the objective of displaying the above output in another component display box; either a textbox or a MathContainer box...  I can see that A() executes, but do not know how to get the result to display in a component box.

Can anyone offer any help?

I want to display calculation steps by maple like this

k=a+b*c=2+4*4=9

How can I do so that when I enter k:=a+b*c (the value of a,b,c have been assigned) and it can show the substitution process and display the result like this

I have three cylinders as follows.

with(plots);
with(plottools);
p1 := cylinder([1, 1, 1], 1, 1);
p2 := cylinder([1, 1, 1], 2, 3);
p3 := cylinder([1, 1, 1], 1, 4);

I want to display in order where p1 is at the bottom, then p2, and then p3 on the top of p2. Thank you for your assistance.

How can I stop this text from appearing in the worksheet output?

What is the purpose of this text as it's a GIANT DISTRACTION from my perspective?

 

SAMPLE EXECUTED WORKSHEET OUTPUT:

> with(plots);

> with(geom3d);

outputs lots of blue text...
