## Fourier series and partial sums of numerical value...

How to change this general form to solve :

How to calculate with Maple Fourier coefficients on some numerical valued functions and how to calculate and plot the 3 partial sums :

Function B : on the interval [-phi, phi]

f(x)= NUMERICAL (x – phi/2) + NUMERICAL (x+phi/2)

Function C : on the interval [-phi, phi]

f(x) =  NUMERICAL (x+phi/2)

## Heat equation in 1 dimention - help needed...

I enclose Maple general solution to the PDF heat equation in 1 dimention.

I need corrections of it to enable me to calculate the heat equation in certain conditions :

du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

## How to use UseAssumptions more efficiently?...

I want to solve several systems of equations and force Maple to account for the assumptions which were made for the used parameters.

For example I tried the following:

restart;
with(Statistics):
Y1 := RandomVariable(Beta(nu, omega)):
assume(0 < nu, 0 < omega):
c1:=solve({mu = Mean(Y1), sigma^2 = Variance(Y1)},{nu,omega}, UseAssumptions);

Now the problem is, that UseAssumptions makes a distinction of cases, even if -like in this case- the results do not differ from each other.

## forum...

Hi all,

i would like to modify plot curves with different coloration in the optimization template coming from a maplesim document.

in the startup code of the maple 13 template i tried  to modify code in order to get the plot form with my custom design every time i open it, without the necessity to change again settings after each simulation.

The problem is that in the help section i don't find any examples about changing different expression curve propriety in a list of list and don't understand how to proceed.

Hello, in the attached graph I have scheduled some inequalities, but it shows error, you would know what is that?

## Problem to calculate constants...

Hi,

I try to plot the deflection of a skyscraper. Therefore I need a very long calculation and the constants c_1 to c_14.

In you can see my calculation.

## earthquake hitting skysrcaper simulation...

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.

## Approximation causes a problem in my loop...

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):

## weird plot output...

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

## ?real causes - Kernel Connection Lost...

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

## Numerical Methods within the N body problem...

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

## Does MapleSim has a Document Object Identifier (DO...

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

## how to get the last line fortran expression in the...

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:

## What´s the problem?...

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);
