I am using 17.02. I looked at this question, http://www.mapleprimes.com/questions/35783-Inverse-Cosine-And-Sine-Transform but I do not understand the answer.

I have a function F(w), and want to find f(t) using inverse cosine forurier transform.

Here is F(w)

F:= w-> cos(w*L)*cos(w*x)/(w^6+w^2*k);

All parameters are positive.

How can I use the answer shown above, or another function to find f(t)?

I can offcourse simply apply the definition myself, and I did:

int(F(w)*cos(w*x),w=0..infinity) assuming positive;

but the result is

So it does not converge. And I just wanted to check using a build-in function to verify. Strange than Maple does not have these in its inttrans package.

with(inttrans);

I am trying to use Maple to produce an image that will be part of a math paper.  The final image must be in .eps format.  Whenever I produce a plot in Maple17 and click on it, it looks like the image has the shape of a square (regardless of what's inside it), perhaps with a lot of empty space.  I want an image without a lot of empty space, and I'd like Maple to do this.  If I crop a square image using some other application, it is not going to improve the quality of the image and might hurt it.  

If the answer to question in the Title is "no", can anyone suggest a good way to produce a good .eps image from a Maple plot that is cropped properly to eliminate as much empty space as possible?  I have Photoshop, but I don't know if this is the best way to go.

I wrote a toy file that plots a simple curve.  I'll upload it and provide a link to it.  If you execute the code and click on the image, you'll see that it is a square with a lot of empty space.

Can any workarounds in Maple for debugging the code without procedure? 

With Maple, I tried

solve(sin(Pi*(x+1)/(4*x^2-4*x+2))=cos(Pi*(x-2)/(4*x^2-4*x+2)),x);

And I got

Warning, solutions may have been lost

RootOf(-sin(1/2*Pi*(_Z+1)/(2*_Z^2-2*_Z+1))+cos(1/2*Pi*(_Z-2)/(2*_Z^2-2*_Z+1)))

With Mathematica

Reduce[Sin[(x + 1) \[Pi]/(4 x^2 - 4 x + 2)] == Cos[(x - 2) \[Pi]/(4 x^2 - 4 x + 2)], x, Reals]

I got all solutions.

Hey everybody I am trying to get maple to do some partial differention for me. 

Where 

I have PDEtools on but, it doesnt return an expression correctly. It's I think the problem is because Ψ is a function of (x,y) and f is a function of η and η is a function of x and y . U and ν are constants. v_x and v_y are the x and y velocites. 

What I would like the program to return when I write 

is something along the lines of 

could someone give me a hand on this. I would really apperciate it.

Hi Guys,

I am trying to do the following and here is the issue:

> System*Transfer*Functions;
Power Stage Transfer Function:
> He := s^2/`ωn`^2+s/(`ωn`*Qn)+1;
>
Compensation Netwrok Transfer Function:
> Av := gm*(1+s/`ωcz1`)(1+s/`ωcz2`)/((Cc+Rc)*s*(1+s/`ωcp`));

>
Loop Transfer Function:
> Loop := Vref*RL*(1+s/`ωesr`)*Av/(Vout*Ri*(1+s/`ωp1`)*He);

> sys3 := TransferFunction(Loop);

Warning, transfer-function(s) are not rational-polynomial(s) in s

I want to do the TF and Bode Plot for this complex system... 

I am having trouble getting a certain Maple worksheet to execute.  Using both Maple17 (I think it is 17.02) installed on two separate PC's at home (XP), and using Maple15 via Citrix from a server maintained by my employer, I get a long error message.  It starts:    "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.".  If anyone wants, I can add the entire error message to this question. I don't think I actually have a firewall at home, and this error message doesn't seem to explain why my local copy of Maple is having trouble.

I think I updated my home copy of Maple to Maple 17.02 after I started writing the worksheet and before this problem appeared, so there may be an issue with Maple 17.02.  But this would not seem to explain the trouble I have executing the worksheet using Maple15 via Citrix.

I have uploaded the file.  I removed the output to make it a reasonable length.  I created a "toy" file that plots x^2 from x = 1 to x = 4, and does nothing else, and it works just fine.  I apologize for the length of the file I uploaded, but I don't know exactly what is causing  the error.

Hi,

I'm having some difficulty in figureing our how to store the results of an fsolve computation in an indexed variable that I can access subsequently to perform plots and do other calculations.  I have a do loop that, for every increment, has fsolve calculate five variable  (x,y,z.. )from a set of equations that have been entered.  It does the calculations just fine.  What I can't seem to do is set up an array variable (or other indexed variable like a vector) so that with every increment of the loop the values that fsolve generates for x, y, z  ect. can be stored.  That just doesn't seem to work, what am I getting wrong? Any help would be most appreciated.

Hi,

I need help formulating a biased coin toss.

I want to toss a coin 0 being heads and 1 being tails with probabilty 0.495 of getting heads, how do I show whether heads or tails wins??

Thanks

I tried

solve(log[3+sqrt(8)](3-x)-log[17-6*sqrt(8)](4*x^2+20*x+25)+log[3-sqrt(8)](x^2+x-2)>=0,x);

and got 

Warning, solutions may have been lost

RealRange(-infinity,Open(-5/2)), RealRange(Open(-5/2),Open(-2)), RealRange(Open(1),Open(3))

How can I get the exact the solution?

Dear All,

please help me with my problem. i have quite a big program all parts of which are distributed in the several code edit regions and in the main text. i'd like to find all occurenses of gven text in all open documents including code edit regions. i know how to do it manually by openening each code edit regiong and pressing Ctrl-F. however it is very time consuming and defocuses me apart from my main tasks. i'd prefer to use some combinations of 'hot keys' on the keybord or one or two mouse clicks as for example in MS Visual Studio.  

4(x-7) =6

(2x+3)(2x^2-_5x-3)=0
