Hi

I am trying to define a funciton I'd like to call approx3f that calculates the taylor expansion of a function f(x) around a point "a" up to 3 terms.  So i want this function to be able to recieve a funciton f(x) and a parameter "a" as its input.

I wrote this:

approx5f :=(f,a)-> f(a)+f'(a)*(x-a)+1/2*f''(a)*(x-a)^2

but i think my definition is wrong cuz it doesn't work.  How can i make maple understand f is a function and then input "a" in it and its derivatives.

Is there a general template to follow for extracting scientific data from a website? 

Hi all,

I was wondering how I would introduce the generalized hypergeometric function command in maple ? This is  like HypergeometricPFQ[ {{1 - \[Nu]/2}, {1}, {1, -(\[Nu]/2)}}, {{2, 3/2}, {}, {1 - \[Nu]/2}}, z^2/2, z^2/2]  in Mathematica but when I try to give it in maple I get error messages...

Thanks!

Hi guys! This is my first question in this forum. I'm a newuser so forgive me if my questions are really basic.

I wrote a non linear system with a number of unknowns and I want to find solutions for a set of values attached to x.

Let's say x:=[0.1, 0.2, 0.3]

I know I have to redefine x:=i and write a "do" command like

for i in x_   do s(i):=fsolve({independent equations},{unknowns to be numerically found})

and i have three sets of solutions s(0.1), s(0.2) and s(0.3)

i want to get compute the extended Euclidean of two polynomials and now I am using gcdex, but it takes too much time for big polynomial. For example: alias(a=RootOf(1+z^31+z^23+z^11+z^7+z^2+z^32)); gcdex(x^32,x^32+(a^15+a^11+a^6)*x^31+(a^13+a^10+a^3)*x^23+(a^11+a^7+a^2+1)*x^11+x^7+a^13+a^10+a^3+a^1+1,1,x's','t'); Is there a better way to do this? Thanks Gepo

Hello,

I am using Maple 13 under Linux and cannot seem to plot.  I get a message like

Error, (in plot) type `has_unit` does not exist
 

Furthermore, the Table, Plot, Drawing and Spreadsheet menus are greyed out so I cannot access them.  How can I rectify this?  Are these features disabled for some reason under Linux?

I have to write a program that takes a plain text; that characters are represented on 5 bits. My information vector is of the form W=[a,b,c,d]. the sent vector is of the form C=[x,y,a,z,b,c,d] where x,y,z are parity check elements. I don't know how to get my W

Our previous article described the design of fast algorithms for multiplying and dividing sparse polynomials. We have integrated these algorithms into the expand and divide commands of Maple 14. In this post I want to talk a bit about what you might see when you try Maple 14. Keep in mind that the product isn't released yet and I don't work for Maplesoft, so general disclaimers apply. Nevertheless, one of the first things you may notice is this.

Hey everybody,

I have what seems to me like it should be an incredibly easy question.

In Maple I have a function u(t). What I need to do now is determine the value of t at which u(t) is equal to some already-known value. It seems like it ought to be incredibly easy to do, but I really have no clue how to do this.

Any help would be greatly appreciated!

 

I have Maple 13 that I got with my student license, I am thinking of re-formating my computer, Win7. Do I need to de-authorize Maple first? or what do I do?

how can I write a code in Maple that will take a primitive irreductible polynomial and will output the tables F4, F8, F9 and F16. this is done using Zech's logarithms

 

Hi,

PredictorEstimator := diff(X(t), t) = A.X(t)+B.U+L.(Y-C.X(t)-D.U)

If I want to collect the X(t) in the above non-communative equation, which maple command should I use?

Regards

 

I created two Maple animations in Maple 13 using the command "animate", which I then call with "display". The application works wonderfully. Now I am trying to create a Maplet around this program, and am having trouble finding any information or examples in the Help menu on how to create play buttons and whatever else is needed to successfully make this work. If you could give me some guidance or point me to an example somewhere that would be greatly appreciated.

hello could u help me with this error printf(cat(`$`(`%12.5 f`, 4)), `$`(vij(1, 1)[k], k = 1 .. 4)) Error, (in fprintf) unknown format code ` ` THANKS
