MaplePrimes Questions

 

 Dear all:

   I wonder how to integrate a function

 

f=t1^a1*t2^a2*t3^a3/(1-t1)^b1/(1-t2)^b2/(1-t3)^b3
 

  over the surface

 0<= t1,t2,t3 <=1, t1+t2+t3=1  ?

 

Thanks,

Peter

Hi, does anybody know how I would create an array from a function.. for example:

Say I have the function y = x^2, and I am choosing the points 1-5 for x, how would I make an array to display all the values 1-5 and their corresponding y-values?

Help much appreciated.

Hi!

I want to work with polynomials over galois fields (finite fields). Useing the standard operations for galois fields from the GF package gets really unreadable for lenghly polynomials, so i am looking for something more legible. I think the nicest way would be to define polynomials in a standard way, e.g. y:= x_1+x_2^2 and than later on decide that x_1 and x_2 are elements from a finite field. However i found no way to do this.

But there should be at least two ways to make the polynomials more legible:

Hi,

I am having problem with dsolve when known input functions are supplied. The code works fine in Maple 10, but not in Maple 11. The error I get in Maple 11 is the following:

Error, (in icp) unable to store '0.2800000000000000000000e-1*s[11](t)' when datatype=float[8]

where s[11](t) then is the known function.

Are there any changes in the call of dsolve? I cannot see any changes in the manual.

Thanks in advance!

How do I make a maple procedure that gives me the imagines of the Mobius strip in half and in 1/3's???

Hi!  New user here and would appreciate specifics in what to do for this lab exercise 1.  the following contains a brief intro along with exercise 1 questions.  thanks for any help!

Let f be an arbitrary continuous function defined on an interval [a − δ, a + δ] and suppose

that f has a continuous first derivative on this interval. The equation of the tangent line to

 

my teacher gave us an assignment & i just want to check my answers before graphing it, thanks!
(a) state the domain
(b) are there x and y intercepts
(c) evaluate the limit of f(x) as x--> 0+  (please show)
(d) critical values?
(e) intervals of increase/decrease
(f) relative and absolute extrema
(g) intervals of concavity
(h) inflection?
(i) asymptotes?
(k) range

I have the output

table([(false, true) = false, (true, true) = true, (true, false) = false, (false, false) = false])

 

However, I would like it to appear somewhat like this,

table([
(false, true) = false,
(true, true) = true,
(true, false) = false,
(false, false) = false
]);

 

Is there a way to tell Maple to do that?

Dear Maple users,

I run into a  question how to expand Diff(u*v,t) into Diff(u,t)*v+Diff(v,t)*u in Maple.

Hello,

i would like to find the Taylor expansion for specific functions but I would like to get the result in following form (for example):

1/((1-s)^(1/2)) = Sum( (2*k)!/(k!)^2*2^(-2*k)*s^k, k=0..infinity)

Is there a way how to get generic equation for n-th term of Taylor series?

Thank you.

Hey.

I need to get maple to calculate y = mx+c from  a two given vectors.

I need to use the two given vectors to calculate m of the slope. But i am stuck as i cant calculate c.

I think the American Formula is y = mx + b

c is the Y axis intercept.

As far as i am aware m = diff of x / diff of y?

I was thinking i could use linear algebra to solve the formula. but there are two unknowns, y and c, so not sure how to go about this on.

Any help appreciated. Thanks

I have a matrix (made by Matrix palette)

> LapMatrix := Matrix(3, 3, {(1, 1) = 1/sin(Theta)^2, (1, 2) = -cos(Theta), (1, 3) = 0, (2, 1) = -cos(Theta), (2, 2) = 1/sin(Theta)^2, (2, 3) = 0, (3, 1) = 0, (3, 2) = 0, (3, 3) = 1});

Maple calculated the 3 eigenvalues.

When I typed

(v,e):=Eigenvectors(LapMatrix)

Maple said

Error, (in LinearAlgebra:-LA_Main:-Eigenvectors) expecting either Matrices of rationals, rational functions, radical functions, algebraic numbers, or algebraic functions, or Matrices of complex(numeric) values

Hello!

1) I want to transform a polynomial in variables x_1, ... , x_n into function K^n -> K

Example:

given y[10] := x[10]+x[1]^2+x[2]*x[5]+x[3]*x[8]

i want to view y[10] as a function and evaluate it at point (x_1, ..., x_n)

 

2) Given m such polynomials y[i] I want to define a funktion K^n -> K^m by viewing every y[i] as a coordinate function

Example:

f:=(y[1],...,y[m]) every y[i] beeing a polynomial in x_1, ..., x_n

Hi,

Basically , I was doing some calculation algebracly.

I got some out like " arc(    AAAAAA  , BBBBBB) , arc( CCCCC,  DDDDDDD) "

 

I wonder what the comma between  A ns B mean?

 

meaning arc (AAAAA) and acr (BBBB)??

 

dose that mean I have 4 answer?

I was solving some sin,cos function

I can find the numerical values of the answer
