In the application example SignalGeneration, I click on the button "Play Waveform" and get the message "This option is only available on the Windows platform. Your platform is X86 64 WINDOWS". Does it really mean that I won't be able to play audio file in windows 7 64? If not, how can I solve this problem ?

Thank you!

How to find the exact solution from this equations?

1. (x+epsilon*y)dy/dx + y =0      y(1)=1

2. (x^n + epsilon * y)dy/dx + nx^(n-1) * y = m*x^(m-1)      y(1)=b>1   ; n=2,3,4,...   ; m=0,1,2,3,...

3. u" + u + epsilon*u^3 = 0    u(0)=A  ;   u'(0)=0

4. y" + 2(y')^2 +3y' = -sin x    ; y(0)=1  ;  y'(0)=0

Would someone be kind enough to write rsolve procedures (or code) to evaluate these two sums

the answers are 3 and 7/4

Doing a pointplot([x1,...,xn],[y1,...yn]) is no problem but I have lists [y11,...y1n] [y21,...,y2n] ... [ym1,...ymn] each be plottet at [x1,...,xm] in 1 plot.

That means:

plotting 

[y11,...y1n] at x1

[y21,...,y2n] at x2

.

.

.

[ym1,...ymn] at xm

What is the easiest way to implement this?

Hello everyone!  

I am very new to the maplesoft community but am very impressed with everything I have learned in the last few days.  I'm having an issue using force probes on a double wishbone suspension that I'm hoping someone can help me with.  I am trying to measure the forces in each link to gather quantitative solutions for the forces at the chassis connection points.  However, I keep getting one of the links measuring no value at all.  The...

 hi everyone,   

I have a list of coordinates  and would like to sort them so that in the new order, the last coordinate will be the first coordinate and the first coordinate will be the first: 

   for example:  

  P:=array([[1,4],[2,3],[3,2],[4,1],[6,5],[6,1]]):   

should sort to  

  P:=array[ [6,1], [6,5], [4,1],[3,2],[2,3],[1,4]]  

Two examples:

for i in {1, 2/0, -3, 1/4, 5} do

if i::posint then print(i)  fi;

od;

       Error, numeric exception: division by zero

select(x->is(x::posint), {1, 2/0, -3, 1/4, 5});

       Error, numeric exception: division by zero

How to avoid interruption of the program in such cases?

Hi, this question requires the use of with(geom3d): package and i don't know how to go about answering it.

Hello dear,

I want to plot a piecewise function.

The code is 

restart:with(plots):

lambda0:=PL-R3*x;

Psi0:=PL+R3*S0*(R1-1)-R1*R3*x;

S0:=(Q-1)/Q;

P:=piecewise(x<S0,lambda0,x>S0,Psi0);

R3=-5,k=4,R1=0.0006,Q=1.2

I want to plot P vs x (0..1) vs PL (0..1).

Thanks

I am trying to illustrate the effects of using finite-precision arithmetic on solving certain linear systems using elementary row operations. I am able to set Digits to the desired level and use the RowOperation command for each individual row operation. I would like to be use say, ReducedRowEchelonForm or LinearSolve with the desired level of precision. Is there anyway to force Maple to use whatever number of digits when using commands like ReducedRowEchelonForm or LinearSolve?...

HelloI have Mathematica code(notebook) I want to convert it to Maple code (worksheet)
 Thanks 

The line continuation character when programming in Maple is the backslash `\`. When using the new Maple IDE within Eclipse, the backslash `\` is not recognized as the line continuation character and causes syntax checking errors. The code within Maple IDE compiles correctly with this line continuation character as you'd expect.

Does anyone know how to add syntax support for line continuation `\` within the new Eclipse Maple IDE?

Example:

tTable := (...

Now I have written this for loop just intuitively but unfortunately it doesnt work:

x(0):=0.5

for N from 1 to 100 do

x:=proc(n) option remember; eval(r*x(n-1)*(1-x(n-1)),r=4/(100)*N) end proc;

l(N):=[seq(x(n),n=20..100)]

end:

What's the specific problem maple has?

Edit: problem solved: 

for N from 1 to 100 do

x:=proc(n) option remember; eval(r*x(n-1)*(1-x(n-1)),r=4/(100)*N) end proc;

Hey guys,

I have the following problem:

I would like to know whether the derivative (e) is negative (given certain assumptions). 

e := diff(((d1-pfw1*Kw-pfs1*Ks-1/3*(d1-pfw1*Kw-pfs1*Ks+d2-pfw2*Kw-pfs2*Ks+d3-pfw3*Kw-pfs3*Ks))*(pf1w-1/3*(pfw1+pfw2+pfw3))+(d2-pfw2*Kw-pfs2*Ks-1/3*(d1-pfw1*Kw-pfs1*Ks+d2-pfw2*Kw-pfs2*Ks+d3-pfw3*Kw-pfs3*Ks))*(pf2w-1/3*(pfw1+pfw2+pfw3))+(d3-pfw3*Kw-pfs3*Ks-1/3*(d1-pfw1*Kw-pfs1*Ks+d2-pfw2*Kw-pfs2*Ks+d3-pfw3*Kw-pfs3*Ks))*(pf3w-1/3*(pfw1+pfw2+pfw3...

I have no idea about how to go about this question, any help is appreciated thanks.
