Hi all,

I am trying to check a conditional statement in maple, I know it is true but my teacher has us do the entire assignment in maple. I am proving the alternating series test of convergence for a series and need to show that the Un's are all positive so

I am trying to check this statement for truth:

5/sqrt(x+4) > 0 for all real values x > 1

Hi
I run Maple 15 on an Acer laptop with Windows 7 and have the following problem:

When my Maple documents become "too" long, some of the vectors I have created seem to become tables instead (without me doing anything) rendering vector multiplications and additions/subtractions impossible (they'll throw an error; something like it not being possible to multiply a vector and a table. As if one of the vectors in my multiplication has become a table). Should it...

Dear Sir/Madam,

I have a list with positive and negative values. Now I want to count the amount of values less than 0. I tried a few things from the ListTools but nothing is working. I hope you can point me in the right direction.

Kind regards,

how can I caculate the Clifford Algebra in using symbolic expression?

Can maple solve this kind of inequality:
piecewise(x > k, x-k, 0) > q * piecewise(x*(1+a) - k > 0, x*(1+a) - k, 0) + p * piecewise(x*(1+b) - k > 0, x*(1+a) - k, 0)
where p, q, a, b, k are parameters?

I'm trying solve-command with allsolutions option but it doesn't work :(

Thanks for answering :)

Hi

How can I use loop-varible in a definition of piecewise function? For example, when I do:

for k to 5 do

f[k] := x -> piecewise(x > 0, k, 0);

end do;

f[3](1);

f[2](1);

I get:

f[3](1) = 6

f[2](1) = 6

Hello everyone, I am new on Maple, I am trying to solve a system of six nonlinear algebraic euqation..and can't get it to work..if someone can help me.. model2.mw

i define two variables as follow:

restart:

omega:=1

omega[i]:=2

i find the 'omega' i had defined  renewd by

omega:=table[i=1]

then type:

omega,omega[i]

result is:    omega, 2

how can i define these two variables in one worksheet?

hello everyone, I have a numerical methids exam in acouple of hours and I just dound out that maple 11 on our campus computers has an old student package tht doesnt include numercalanalysis , is there anyway to update it ?

Hi everyone,

I would like to do:

f:=unapply(x**2,x);
j:=unapply(2*f(x),f(x));

Basically it is to define j(f(x))

But this is doesn't work. What is the right way to do it?\

My final goal is to calculate int(j(f(x)), f(x)=-infinity..infinity).

I have the following lines of code:

W:=sum((k^(2*i))*sum((e^(j))*w[i,j](r,t),j=0..2),i=0..2);

P:=sum((k^(2*i+1))*sum((e^(j))*w[i,j](r,t),j=0..2),i=0..2);

for c from 0 to 2 do

  for d from 0 to 2 do

    rw[c,d]:=coeff(coeff((k/(2*r))*(diff(W,r)*diff(P,t)-diff(W,t)*diff(P,r)),k,2*c),e,d)

  end do

end do;

I mean to compute the coefficients in front of powers of e inside...

Hi everyone,

Is it possible to perform an integral over vector without writing a multiple integral over each component?

I am integrating over a vector of dimension 12, so I am trying to find another way to calculate rather than writing 12 integrals.

Thanks

Please write for me a code for the following problem.

Let (S): x^2 + y^2 + z^2 -2*x +2*z + 1 = 0 be a sphere and M(1, 2, -1), N(3, 1, -1) be two points. Find the coordinates of the point K lies on the sphere (S) such that the triangle KHN has minimum area. 

Thank you very much.

Hi!

Probably trivial, ...but how to set up a slider in degrees.
I'd like to use degrees instead radians in expresion ...from some reasons.
Help will be apreciated :-)

Hello, 

I am fairly new to using Maple and am a university student. Bascially, I wanted to ask, how can I solve for all roots of the transcendental equation
