MaplePrimes Questions


Dear Mapleprimes

I am working on getting the right angles for my gears to fit together. My problem is that my fsolve (at the bottom of the page) does not seem to work. Can you help me by telling me what I am doing wrong.

Hi

I want to allocate the result of "solve" command to a variable (array)

u := eval(solve({x-y = -1, 2*x-y = 3}, {x, y}));

                                                                     ...

By a straight forward calculation, one can check that the expressions

(2*delta^2-2*beta*delta+alpha^2-2*alpha*delta+beta^2)*N^2+2*gamma*(beta+alpha-2*delta)*N+2*gamma^2

 

and 

 

(N*beta-N*delta+gamma)^2+(N*(alpha-delta)+gamma)^2

 

are same and equal. 

How to get the 2nd expression from the 1st expression by simplification by using MAPLE. 

Hello I am working on a Physical Chemsitry problem and Am haveing trouble evaluateing a statistical mechanics approach to calulating entropy. I have defined a list Z that contains 12 values for a variable that is used to descirbe a state. The sum:


sum((ln(1-exp(Z[i]/T)),i=1..12)

is supposed to give me the entropy of a system with those 12 possible states (T is Temperature which is to be entered later) When i try to evaluate this (where the value that changes is defined by a list...

Howdy.........Is there anyway i can force Maple simplify the LHS to equal the RHS. I know the're equivalent, but the RHS is neater IMHO.

(1/3)*sqrt(3) = 1/sqrt(3)

 

Hi, I was about to calculate the limit

 

limit(sin(x)+sin(y),{x=0,y=0})

 

and Maple 17 returns the same expression, with no answer.

 

What I am doing wrong?

As showed in attached file

the laurent series of exp(1/z) at z=1 is equal to the taylor series of exp(z) at z=1           

Hello every one, 

Here I will recall the PDE and its numerical solutiion provided by Maple help. 

PDE := diff(u(x,t),t)=-diff(u(x,t),x);

IBC := {u(x,0)=sin(2*Pi*x),u(0,t)=-sin(2*Pi*t)};

pds := pdsolve(PDE,IBC,numeric,time=t,range=0..1);

p1:=pds:-plot(t=0,numpoints=50):
p2:=pds:-plot(t=1/8,numpoints=50,color=blue):
p3:=pds:-plot(t=1/4,numpoints=50,color=green):
plots[display]({p1,p2,p3});

I want to export data...

Hi,

I posted a problem the other day to do with this specific problem and the issues got sorted out:)

The aim of the program is to find the catenary by iteration...

It's majorly diverging though and i'm not sure why.

Any ideas?

Thanks,

Rach

Trying_to_get_the_Ca.mw

I have been trying to figure out how to use the flexible beam properly. I'm looking for a clear example on how to actually use this component. I have had no luck so far. I must be be missing something. 

 

The current example, http://www.mapleprimes.com/questions/94996-Flexible-Robot-Arm, does not really show much. 

 

Does someone have a simple example? Perhaps using the Flexible Beam as a cantilever, with one end fixed...

Sometimes maple tends to press enter two times when I want to access a label with Ctrl+L

Here is what I mean:

This happened because it "pressed" enter 2 times. This doesn't happen all the time. Did anybody have this problem? Any way to fix it?

P.S. My space bar is alright 100%

Iexported as LaTex and get the following file. When I use TeXmaker run, the pdffile not full out put the result. It can not break page.

Hi everyone

It's been a while since I last used Maple, so maybe these are simple questions

The first is:

I have a DE

eqbz:=diff(y(x),x)=-l/x^2*(y(x)^2-yeq(x)^2)

yeq(x) is a simple function of x and I want to solve it with "l" as a parameter and ic:=y(0.01)=1

sol:=dsolve({eqbz,ic},numeric,output=listprocedure,range=0.01..10^3,parameters=[l])

then I proceed to plot

ysol:=eval(y(x),sol)

ysol(parameters=[l=x]):

I have two lists viz.

m:=[0,1,2,3,4,5]; n:=[0,1,2,3,4,5,6,7,8,9];

I have to define a mapping (i.e. a Maple table) say `p` such that

(1) p(0)=0,

(2) p(max(m))=p(max(n)) and

(3) For all other i in m p(i) is a random choice from n but with condition that p(i)>=p(i-1).

Help is desperately needed. regards
