Hi i'm trying to code the jacobi method but my code dosen't work. Nothing happens. What hav i done wrong

And in worksheet mode,or after click the Ctrl+J,ie insert Maple Input,

I can't use ctrl+=,that generate the results at the right hand.

Pic2 is the one after creating document block

How do I solve for the Lagrange multipliers of

f(x,y,z)= xyz +x^2 + y^3 +z^4

subject to the constraints:

g(x,y,z)= x^2 + y^2 + 2z^2=4

h(x,y,z) = 3yz + 2xz + xy =6

I've never used maple before so am completely lost and need to do this for an assignment=)

thanks

I'd like to start by thanking all those readers who left feedback on my last post. It was good hear that most of you enjoy reading my posts and that they are generally helpful. I would like to encourage you to continue posting feedback, especially questions or comments about anything that I fail to explain sufficiently.

The following is a discussion of the limitations of parallel programming in Maple. These are the issues that we are aware of and are hoping to fix in future releases.

I have two sets A={a,b,c} and B={w,x,y,z}. I have to make sets like following

{(w,{a,c}), (y,{a,b,c}), (z,{b})}

 How I can know the total number of such sets from A and B?

let F(n) is the nth fibonacci number. what is the limit

lim(n->infinity) f(n-1) / f(n+2)

For the comand:

plot({[2-3*sin(t), t, t = 0 .. 2*Pi], [2-3*cos(t), t, t = 0 .. 2*Pi]}, scaling = constrained, coords = polar)

Alright people im really stuck on this maple question and i was wondering if any of you lot could help me out :)
Im really new to maple and ive been attempting this question for ages with various google searches etc..
Help will be appricated greatly

Hi

I must work with the textual version of Maple, via ssh. My program asks for a lot of time (10^5 seconds) , so that  I usally let it to run all the night. What happens is that when the calculation is done, the ssh server close the connection due to time inactivity, and I can't either use the results or continue my work there.

My questions are then:

1) Can I set Maple to keep the connection alive?

for wha m the following inequality holds

(1+x)^(m+1) > 2^m*(x^m+x)

1<=x<=2

Hi,

I'm new with maple.

I'm trying to solve a nonlinear system of equations (4x4). I tried fsolve and solve but neither work :'(

Could someone give me a hand?

Thanks!!!

Ignacio

Hi, I have a system of four first order, nonlinear, differential equations with four dependent variables.  The variable F(t) can be set equal to zero or to some known function. 

A*(diff(xx(t), t)) + epsilon*xx(t) + B*(diff(phi(t), t))*cos(theta(t)) + C*phi(t)^2*sin(theta(t)) = F(t),

D*(diff(xx(t), t))*cos(theta(t)) + E*diff(phi(t), t)) + F*sin(theta(t)) = 0,

xx(t) = diff(x(t), t),

phi(t) = diff(theta(t), t)

Can anyone tell me if

plot((4*x+4)*(u(x+2)-u(x))+4*(u(x)-u(x -2)),x=-5..5);

is the correct syntax to plot question a) shown in

Any help is appreciated

Thank you
