Hello people, Recently I recieved some help with binomial-solutions. I will most likely come with more questions while I'm working my way through my homework. In a bag there are 4 red marbles, 5 blue balls and 6 white balls. We select randomly and simultaneously 3 balls from the bag. What is the probability for each of the following events; a) The 3 balls have different colors. I did: binomial(4, 1)*binomial(5, 1)*binomial(6, 1)/binomial(15, 3) b) The 3 balls are all the same color. I did: (binomial(4, 3)+binomial(5, 3)+binomial(6, 3))/binomial(15, 3)

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

Hi, I'm having a problem with the styles I set as default reverting to factory conditions after I close and reopen Maple. For instance, if i set the font to Calibri and make it my default Text font, it will revert back to Times New Roman when I open Maple again. Thanks

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

 

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
