There are 10 questions. each question has one negetive point and three positive points. what is the number of students so that there will not be any repeatitive grades so all the students have distinct grades. Thanks in advance

## Code conversion From Python...

Hello Everyone,

I am new to Maple and I have designed an algorithm to compute multivariate differential dimension Grobner bases. Now I want to add this Maple as a package but I do not how to do that.

Thank you so much for your help.

My code can be found at https://github.com/Gsparsh/Grobner-bases

## How to generate a vector by calculating the entrie...

Hi,

I am a newbie and therefore have a rather simple question for the community:

By reading in my measurement data (topographic data) I have generated column vectors:
for i from 1 to k do
B[i] := Vector(A[1 .. k, i]);
end do:
where k is a predefined rank of the original square matrix. The arithmetic mean was then calculated for each individual column vector:
for i from 1 to k do
Am[i] := add(B[i][n], n = 1 .. k)/k;
end do:

Now I try to create new column vectors by subtracting the corresponding mean value from each entry of the original vectors, something like that:
for i from 1 to k do
C[i]:=B[i][n]-Am[i],n=1..k

But I just can't get it right. Can anyone help me? Thanks in advance!

Cheers
Christian

## How to make entries in the last row to be the sam...

For example, the column dimension is 6 and I ran the following command,

A := Mod(2,Matrix(3,6,(i,j)->if i<2 and j < 3 then 1  elif i = 2 and j > 2 and j <5 then 1 else 0 end if),float[8])

the result is the following matrix with the last row containing all 0s.

A := Matrix(3, 6, [[1., 1., 0., 0., 0., 0.], [0., 0., 1., 1., 0., 0.], [0., 0., 0., 0., 0., 0.]])
Actually, I want the last row containing all 1s but I do not know how.
Any help?

## question regarding completeSquare command?...

I if a run the CompleteSquare command

CompleteSquare(x^2 + y^2 - 2*x - y - 2 = 10, x, y)

the output is (y - 1/2)^2 + (x - 1)^2 - 13/4 = 10

Why does it places the y's before the x's?

## Gcd of polynomials with scalars...

How do I compute the gcd of polynomials with scalars e.g. how to compute gcd (x^9-a, bx^6-c )  as polynomials in x.   https://www.maplesoft.com/support/help/Maple/view.aspx?path=Task/GCDofPolynomials   here I don't see how to specify the polynomials are in x.

Hi everyone, I have a problem in the code solving coupled partial differential equations. I could not find out the solution. Please help me out with this. Find the code in the attachment.

## 2nd derivative implicit differentiation...

I didn't understand what the page on implicit differentiation meant by 2nd derivatives are just like in using diff    Like this  implicitdiff(y^2 = x^3+a*x+b, y, x, [x\$n]) ??  idk

## Using Maple to solve a Second Order ODE...

I have the following ODE which I would like to solve with Maple rather than solving by hand (having solved this type of equation by hand many times now):

diff(f(x,y,z),z\$2) = A - B*e^(-A*z)

where A and B are constants and I have indicated the second derivative of a function of x,y and z with respect to z.

## Plot is not matching...

Dear maple users,
Greetings.
I am solving an ode problem with an analytical solution.
programming running properly, but my plot not exact with the already existing article plot.
how to get the exact plot.

Thanking you.

Code:JVB.mw
