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?

Good morning sir,

I request you to provide the correct Maple proc to generate the Gershgorin circles for a given

Square Matrix

Good morning sir,

I request your support for the above cited subject.

Once a plot is generated using Maple commands for a certain problem, to lable the axes

I am facing the problem to lable at the desired positions on the graph.

Good morning sir,

I request you to provide the Maple Proc to solve the equations by Muller's method because it requires three 

initial approximations and the iteration process is very much tedious to get the desired accurate approximation.

I am having trouble getting Maple to work with fractional exponents.  When I ask Maple to compute 8^(2/3) and 8^(1/3), it just echoes my input, instead of returning 4 and 2, respectively, as it should (I think the overwhelming majority of mathematicians would agree that Maple should return 4 and 2.  It is conventional not to consider complex numbers when defining, e.g.,  "8^(1/3)" unless a problem specifies that you need to consider complex numbers).  When I ask for 4^(1/2...

This blog post is a response to a post on MaplePrimes.  MaplePrimes user wkehowski asked how the Task Model could be used to filter combinations.  The basic problem is formalated like this:  We want a function, I'll call it FilterComb, that accepts positive integers...

Hi all,

I'm getting started with maple. Want to solve the following integral:

int(     (  1+(a*x)^t  )^(-1/t)      , x = 0 .. z)

Constraint: 0<t<1

Maple 8 installed on an old WinXP gave me a solution with

hypergeometric functions. Maple 17 installed on a Linux64

gave me no answer at all. What could explain this difference?

Thx...

Hi,

New to maple and I have 2 questions that I'm stuck on.

1) Find the principal arguments of the 5 roots of the polynomial

and enter a decimal approximation to the largest principal argument in the box below.

ans: 2.589502038

2) Find the moduli of the 5 roots of the polynomial

and enter a decimal approximation to the largest modulus in the box below

ans: 2.34880159160143

I dont really know what to write in maple to get the answer. So, if someone could help me out that would be really great. cheers

This is what i have done to find the difference between a ball thrown with different starting angle, and then ploted they into the same plot.

restart; Digits:=20: with(plots):

C_0:=0.4: d:=0.0002: mu:=1.8*10^(-5): rho:=1.2: g:= 9.81:
rho_v:=1000.0: m:=evalf((4/3)*Pi*rho_v*(d/2)^3):   


F_D:=proc(v::list)                 
local k,vx,vy; 
vx:=v[1]; 
vy:=v[2]; 

This is my approach:

sum(1/(4*n+1/3*k),k=1..infinity)

but I end up getting infinity for my answer which is obviously wrong.
