Hi,

I try to solve the folowing task:

Simulate the behaviour of a skyscraper with eight floors during an earthquake. (assumption: cosinus stimulation). Determine the resonance frequency of the skyscraper. When does it collapse. Ignore damping.

Hi everyone.

I have a loop in which initial data of ODE is found on every iteration and is substituted to find new solution. The system is striking 1 or -1 and x'(t) changes its sign, to -x'(t)

I do it this way (k[i] stands for the values of time t):

Hi, I was trying to define a function defined as a Fourier transform. In the plot, there are several pieces of the curve missing.

 

Anyone else experience this same issue?

If you type ?real

it causes a maple error box to pop up

Kernel Connection Lost
*Kernel connection has been lost.
You should save this worksheet and restart Maple.
Executing commands in Maple requires a connection to the Maple kernel.
Firewalls have been known to cause problems with kernel connections in
Maple. Please ensure that any firewall software is configured to allow
Maple to create connections to the kernel. Consult the FAQ for more
information.

Help me, thank a lot

I am looking for help with basic algorithms to approximate numerical solution to the N body problem. I have been trying to develop basic algorithms using Runge Kutta, Euler ect. Initially I specified to the 3 body case and the equations of motion. I am now trying to develop a more general algorithm. If anyone has knowledge in this are or can look through my annotated procedure to see where I have gone wrong I would appreciate it. I am very new to maple and would appreciate detailed exposition, "for dummy's", if you will. Thanks in advance

Hello,

I am wrting my thesis which is on some MapleSim models. In Ref I introduce MapleSim, I wanna know if MapleSim has Document Object Identifier (DOI) number or name that I can refer to.

Thanks so much,

Bye

Hello, recently I am working to write a bash shell program combined with maple to automatically produce the codes to calculate functional and functional derivatives values for some given functional expression(This is provided by the user in maple input file). Now I meet a problem.

Take the codes below as an example:

I tried the following:

restart;
with(Statistics):
X1 := RandomVariable(Binomial(n, p)):
DARA := t->piecewise(0<t,log(t),0):

0 < n, n::posint, 0 <= p, p <= 1:
 

ExpectedValue(DARA(X1));                                        
g1 := simplify(%) = DARA(s);
k1 := solve(g1, s);
 

Hello, In maple, I am defining a differential equation similar to: (x^2)*diff(y(x), x$2)+x*diff(y(x),x)= a cubic in y(x). When I try to solve this using dsolve, numeric, I receive some form of memory error, stating that something small*I cannot be stored in datatype = float[8]. Sorry this isn't too specific - if you need more info or the boundary conditions, or perhaps the error message word-for-word, I'll reply with it when I get to my other laptop. Thank you very much for your help in advance, Marc

Hey guys i am currently attempting to do some modelling with maple, i need to solve a PDE system, i am using the following code and am confused with the error i'm getting. restart: M[Star]:=2*10^30: M[planet]:=2*10^27: q:=(M[planet])/(M[Star]): g:=sqrt((R-a)^(2)): H:=0.0333*R^(1): Delta[p]:=H: Alpha := unapply(piecewise(R <> a, 6.67*q^2*10^(-11)*M[Star]*(a/Delta[p])^4/(2*R), R = a, 1), R, a)

How do I select multiple non-contiguous lines of text (or math).  I have tried cntrl-slect, shift-select, anything I can think of -select with no success.

Thanks in advance.

Hello! I have a problem - i can't find standart Maple functions and procedures, that plot, so to speak, "phase portrait"-esque magnetic field lines for featured "vector field". In details: i need to plot magnetic field lines and equipotential curves of uniformly magnetized cylinder. I have piecewise functions Hr(r,z) and Hz(r,z), (per se, r is x, z is y, y-axis coincides with cylinder axis): L := 2; a := .5

Hi

Does anyone know how to export surface plot with multible surfaces to a file format that can be easily plotted using matlab?

Thanks in advance
