Find all integers a, b, c that satisfies the following condition. [condition] For all positive integer n, a4^n+b6^n+c9^n is a perfect square.

Hi,

I have a function of n variables

y := (a,b .. n) → ....

For this function I need also n input values

y(x1,x2, ... ,xn)

The vector x has the input values ("x1,x2, ... ,xn") but how can I call them without typing them one by one?

Any ideas?

LegendreP(m-1/2, l+1/2, coth(x))/sqrt(sinh(x))

I want to calculate the series about x=0 but I get the error 

Error, (in MultiSeries:-multiseries) need to determine the sign of, 2*m

What problem does maple encounter here?

I tried assume(m>0) and then I got the error

Error, (in MultiSeries:-multiseries) need to determine the sign of, 1-2*m

Hi!

Within a for-loop I want to sum a column for a matrix, but using the column number j gives a error:

"Error, (in tools/add) bad index into Matrix"

script:

for j from 1 to J do

<<>>

Y[1, j] := sum('X[i,j]', i = 1 .. n)

<<>>

end do

Any solutions? Thanks!

How does one find a formula that  fits a given set of data  to the best advantage in Maple? 

e.g

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

b := [ 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011];

c := [ -0.88, -8.87, -0.86, -0.82, -0.77, -0.71, -0.66, -0.62, -0.57, -0.54, -0.89, -0.88, -0.85, -0.81,...

I want to simplify my equations in Maple

In case of MATLAB i can write

a= 1:0.5:150;

 e= [0.001 0.05 0.151 0.201 0.301 0.951 2];

s= kron([e], ones(1, 12));

But, how to write and create matrix in this form using Maple? 

Thanks in advance

2014! How many Zero in that number?

Hello,

To simplify and try to keep my program structured, i use sections. I often need to desactive all the lines codes of a section. Is there a soluion to desactive many lines in the same time without putting this # to each line.

Thank you for your help.

We’re conducting some market research, and we’re hoping some of you can help.  We’re interested in learning more about why people choose Maple over other systems, in particular Mathematica.  We know why we like Maple, but we’re interested in knowing why you do.

We’d love to hear from anyone who either compared both systems before choosing Maple or who used to be a Mathematica user and has now switched to Maple.  What led you to make your decision?

I thought I would generate a fun problem for Maple, and see what coding we could come up with.

You happen to be at work one day and overhear the managers talking about taking sick days away from the employees because everyone is taking their sick time around weekends.  The managers have decided to take one more years worth of data before making their decision. 

So you've decided to build a program in Maple for all the employees to use so that...

Is it possible to use printf to get math 2d output? For example, I'm writing a loop computing Riemann Sums.

f := x-> x^2; a := 0; b := 1; for i from 1 to 5 do printf("f(x[%d])=%a",i,f(a+i*(b-a)/5)*(b-a)/5); end do;

I would like the output to look nicer. Thanks in advance!

How to create a polynomial for the curve fitting of the 3D plot in Maple?

I have following data

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

b := [ 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011];
