How do i make 3d kink kink collition soliton  animation  graph in maple.

Hi 

I have 3 equations

eq1 := vs = (Rs+Z)*i1+Z*i3

eq2 := A*vi = Z*i1+(Z+Rf+ro)*i3

eq3:= vo = (Rf+Z)*i3+Z*i1

 

and I want to solve for vo/vs . How to do that ?

the expected solution is 

If you're hear your dog, request your child and over a walk, What do you notice? Gruhn is suggested by ”. Then supply the response: Pet. Bark. Ruff! Ruff!” Do your child as well as this each and every time a woofing pet is encountered by you will probably start addressing with all the (Ruff! Eventually, they'll polish his reaction to dog.” Here Is Another comparable approach to educate them about real sounds. If it begins drizzling before you operate for cover while you're out, allow them feel the mist on his face. They wont dissolve. Say, Feel the water. Rainwater. Wet.” Next protect the bustle and buggy residence. http://www.healthyminimarket.com/neuro-nzt/


Please help me to solve this integration

restart; with(LinearAlgebra); int(exp(-(ln(z/(snr*B^2))+4*sigma^2)^2/(32*sigma^2))*eta^2*(y/z)^((1/2)*eta^2-1)/(z*sqrt(32*Pi*sigma^2)*(2*sqrt(y*z))*(2*A[o]^(eta^2))), z, z = y/A[o]^2 .. infinity);

Review the price they're asking. Be cautious and examine that in your anti-aging products system you might have product which are likely to feed the Skin Care Tips rather than diminish the water out of it.

Citratone An overnight lotion is so used by quality rest, while a fantastic gain to your body-mind produces an excess number of oil on the skin to wake-up using a more healthy tone. Hormones basically surge while asleep and will cover skin with glow that is much it truly is frustrating and can positively exaggerate oily and acne skin problems.

I'm trying to execute the program, which can be found here http://www.maplesoft.com/support/help/Maple/view.aspx?path=examples/pdsolve_boundaryconditions , but it does not work. I copied exactly what is written there:

restart; with(PDEtools):
U := diff_table(u(x,t)):
pde[1] := U[t]+c*U[x]=-lambda*U[];
bc[1] := eval(U[], t=0) = phi(x);
sys[1] := [pde[1], bc[1]];
pdsolve(sys[1]);

But after last command it just sais that

Error, (in pdsolve/sys/info) found functions with same name but depending on different arguments in the given DE system: [u(x,t), u(x,0)]

What's wrong?

Dear Community Members,

 

We have problem with calculation in Maple v11 and v18. when we make a calculation by using maple v11 and v18, we was not able to get the solution as you see enclosed. when we clicked to "enter + ; ", programme does not run.

 

Hello

I have a loop with the do structure but there is an error in the loop .

how can I continue the loop by error or disregard it?

Hello,

 

could you help me solve this error ? I don't understand what it means.

 


> eq3:=diff(x(t),t,t)+Gamma*diff(x(t),t)+omega[0]^2*(x(t)-(diff(x(t),t,t)+Gamma*diff(x(t),t)+omega[0]^2*x(t)+omega[0]^2*X[0])/omega[0]^2) = -omega[0]^2*X[0]:

Thanks.

I have a great problem with this integral and Maple gives two answers completely different:

 

int(x^-5/3*cos((x-1)*h), x = 0..infinity)

so I get two different results :

 

-(27/8)*h^2+3/2+(27/8)*h^(7/6)*LommelS2(11/6, 1/2, h)

 

or this:

 

-(27/8)*h^2+3/2+(27/8)*h^(7/6)*LommelS1(11/6, 1/2, h)

In the first integral A get Lommels2 and If I get the Integral by using Taylor of cos((x-1)*h) and after that I resum I get Lommels1.

 

Thank you.

 

 

 

Greetings everyone. I tried to get the roots of this polynomial by using allvalues command. But I got the roots in indeces instead of the value of the roots.

what should i do?

Hello! I wrote a program in Maple but it doesn't work. It crashes with the following error: "Error, (in r_nach_1[3]) too many levels of recursion". I am a newbie in Maple and don't know how to solve this problem. A part of my program that causes the error is given below. Many thanks!

Hi, im new with maple

so I am still a bit confused with how to use it..

i have an nonlinear ODE with parameter "b"

(x+b*y(x))dy/dx + y(x) =0 ; y(1)=1

if i want b=0.1 and x=0, 0.1, 0.2, ..,1

how do i
