How to find X*Z-Y^2, Y*W-Z^2, X*W - Y*Z

Let a,b and c be the three roots of the equation :2012x^3+2013x+2014=0.Find (a+b)^3+(b+c)^3+(c+a)^3?

hello..

i have promblem, how i convert string to matrix and then, seprate row in matrix..

for example
a:=["0101101","0000101","0001001"]
 i want convert to matrix like..

Hello..
 i have big problem, i dont know, how to add 0 in front.
firstly, i convert decimal to binary and  then i convert to string

but, how i add some 0 in front??
for exmple below..

list:=["1000","1","1110"]

i want to look like 7 bit
["0001000","0000001","0001110"]

i dont know how to count all digit, and how to add some 0 to front , and also have 7 bit?

okay so i have to write a maple function that decides wheter a line given by a vector that spans it intersects a triangle with given vertices. 

an example of what it should look it is 

ISC([[0,0],[10,10],[10,10]],[2,1]) returns true

ISC([[0,0],[10,10],[10,0]],[-2,1]) returns false

thanks in advance.  i'm just having severe problems with writing functions and what not as you can tell. anyway, Thanks!!

okay so the question i have to answer is "write a maple function that computes the area of a triangle in the plane from the coordinates of the vertices"  

ive gotten this far 

with(geometry);

triangle(ABC, [point(A, 0, 0), point(B, 2, 0), point(C, 1, 3)]);

area(ABC);    3

but how can i write so when you type say AA([[0,0],[10,10],[10,0]])  it returns  50?  (AA being the function name)

Thanks in advance to whoever helps.

I have asked this question before (2008) but no one answered. I just repeated my error and am still flummoxedflummoxed.

In early versions of Maple (Maple 1 Maple 3) one could halt a computation on the Mac by holding down the command key and the period; Maple would respond quickly. Now one can try that or click on the red hand in the tool bar and interrupt the computation but it doen not necessarily stop.

I inserted a print command in a procedure so that I culd...

Can anybody tell me what error is in the following function?

F:= ([[a,b], [c,d], [e,f]]) -> (1/2) abs((c-a)(f-b)-(e-a)(d-b));

Thank you!

Good afternoon sir,

I would like to the usage and purpose of the maple tool with(MTM)

I request your kind support in this regard.

Good morning sir.

This is just to get awareness that can we able to generate the Greshgorin circles for a given square matrix A

by using direct maple commands in linear algebra package.

I request your kind support in this regard.

I want to fit a function to data which I did with the fit command

f := Fit(1+a*n^b, X, Y, n, output = [leastsquaresfunction])

btw: the output standarderrors does not work...

it produces the error:

Error, (in Statistics:-Fit) values for these items are not available: ["standarderrors"]

Now maple just returns the least square parameters but without errors.

How can I get the errors for the parameters?

So I am working with the OrthgonalExpansions library (amazing library, by the way! Just what I needed!), and it is great, except it seems to be having trouble doing a 2d Fourier expansion.

I'll upload my document. transformApprox.mw

In this document, I am running the BesselSeries expansion as we speak, but the FourierSeries expansion (in 2d) can never seem to complete. It always say that it has an

I am working with a home-brewed program that evaluates magnetic fields from air-core coils. While I have analytic expressions for the field itself, the code involves numeric integration through regions of the field. It also involves adding up the contributions of several coils.

Speed is becoming an issue. I dearly would like to run some of the integrations (which is where the time is spent) in parallel. The contributions from different coils would trivially parallelize,...
