It seems if I copy some text into one of the cells of a maple spreadsheet I get an error.

Specifically the error only occurs if a space exists in the text.  Also entering text with spaces produces the error as well.

hello there - typed into a cell produces   Error, missing operator or ';'

Similarily    5 4 we receive Error unexpected number

There is only two options for the cell properties under type - Symbolic and Floating Point.  Another option to fix this issue would be to have a Label option?  

Hello all!

I did

with(plottools):

display(pieslice([0,0],5,Pi/4..7Pi/4,color=yellow))

but I don't know how to do "Animating Pacman". Can you help me? I read it on Mapleprimes but I don't really understand. Can you explain it to me? Thank you so much! Sorry, My English is not very good

Wonder if this can be accomplished in Maple.

so I have a list of 100 items labeled {1..100} of various value {$100, $160, $220, ......  , }

the task is to distribute these items among 3 people A,B,C so they get an approximately equal share.

Adding the values and dividing by 3 gives the dollar total to aim for. 

This post has C.Love procedure for evenly sized groups

 http://www.mapleprimes.com/questions/200480-Product-Grouping

but what i want is a method for different sized groups. ie 25 items for A, 35 for B and 40 for C (user defined).

additionally there is a fixed constraint: A has been bequeathed items 1,4,8; B items 2 and 20; C item 50.

Hi

When I run a maple file it uses 25% of CPU.

When I run 2 files, the half of CPU is used.

How can I change the preferences for using most of CPU

Hello,

i need help to translate a system which is given below to a for loop.

Other wise i am writing it with myself. 

instead of doing it like that 

with(LinearAlgebra);

sys := [galerkin_funcs[1], galerkin_funcs[2], galerkin_funcs[3], galerkin_funcs[4], galerkin_funcs[5], galerkin_funcs[6], galerkin_funcs[7], galerkin_funcs[8], galerkin_funcs[9], galerkin_funcs[10]];

var := [w[1], w[2], w[3], w[4], w[5], w[6]];

Kmat, Fmat := GenerateMatrix(sys, var);

i want to do it like that.

N:=10

for i to N+4 do

sys(1,i) := galerkin_funcs[i] 

end do

for i to N do

var(1,i) := w[i] 

end do

After that i will generate matrix with this comman Kmat, Fmat := GenerateMatrix(sys, var);

But this for loop i wrote is not doing the i want to do.

Thanks for your help.

Error, (in fsolve/polynom) Digits cannot exceed 38654705646

I am using fsolve to find numerical approximations to the roots of many fairly large polynomials (degrees up to ~80).  I often get this error message and I'm not sure why.  Is there any workaround?  Any help is much appreciated.

Is there a bug for resizing the spreadsheet?  I am unable to drag the size to the full worksheet.  If it's a bug is there a workaround?

How can I generate some n-tuple random list of integers s.t. any component is between -30 and 50? For example if n=5 then four random of such 5-tuple are

[-1,2,8,7,9] , [0,-9,2,-3,-5] , [4,5,3,-8,-1] , [12, -5, 0, 6,8]

I am trying to obtain the splitting field of New_polyq. evala@AFactor did not complete. Applying splitting sequentially produced independent extensions from the first 2 (3?) factors. evala@Indep did not complete for the union of all 4 extensions.

What libraries would handle this better?

hi all

i have a plot and i want  make it symmetry into axes y.

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)));

plot(A,x0=-3..5);

Hi,

I am trying to find the roots of Hankel function H1(2, z)?

j := 1;
for i from 0 to 10 do z0 := i*step+z_min; x[j] := fsolve(f = 0, z = z0, complex) end do;

for p to 10 do for j from p+1 to 9 do if `and`(Re(x[j])-Re(x[p]) < 0.1e-4, Im(x[j])-Im(x[p]) < 0.1e-4) then for i from j to 10 do x[i] := x[i+1] end do; p := p-1; break end if end do end do;

the first of these two processes works fine however the second does not. The second on is to get rid of same value solutions! I am not sure if I have missed anything and also is there a way to determine a max value in the complex domain and use it in a for loop?

any help would be great

After reading

I tried to check this 'trick' in maple, but see what happens in Maple 2015:

 what is the correct solution for 0^0?

Here the code for those who hate typing:

x := 0; 0^(x^2);
0
1
for x from -1 to 1 do print(x, evalf(0^(x^2), 20)) end do;
-1, 0.
0, 1.
1, 0.
for x from -1 by .1 to 1 do print(x, evalf(0^(x^2), 20)) end do;
-1, 0.
-0.9, 0.
-0.8, 0.
-0.7, 0.
-0.6, 0.
-0.5, 0.
-0.4, 0.
-0.3, 0.

Hello all! How to create this plot in Maple?

how can i solve this program?
