Hi, i have been fighting with Maple 11 for a long time and i would like to know if i am doing something wrong or the integral is so complex for the program... I really need to solve this problem soon if i would like to have a successfully Master Thesis :) During the degree i study Maple but i forgot a lot :( Here is the issue: I am working in telecommunication issues and calculating the output power i get this integral: P[through] := int(2.000000000*10^8*(.51-1.428285686*10^(-0.1600000000e-1*Pi)*sqrt(1-k[2]^2)*cos(0.2473600e-2*Pi^2/lambda)+(10^(-0.1600000000e-1*Pi))^2*(1-k[2]^2))/((1-.7141428429*10^(-0.1600000000e-1*Pi)*sqrt(1-k[2]^2))^2*(1+2.856571372*10^(-0.1600000000e-1*Pi)*sqrt(1-k[2]^2)*sin(0.1236800e-2*Pi^2/lambda)^2/(1-.7141428429*10^(-0.1600000000e-1*Pi)*sqrt(1-k[2]^2))^2)), lambda = 6.30*10^(-7) .. 6.35*10^(-7))

For some work I am doing with matrices with polynomial entries in certain parameters, I need to know for which values of the parameters there is a possibility that the rank of the matrix drops down. I tried using fraction free Gaussian elimination in both linalg and LinearAlgebra. The two methods do not always give the same resulting matrix. Moreover, the matrix is not as simple as it should be. I understand that a Gauss-Bareiss algorithm produces a result which I would be happier with. Does anyone know of such an implementation for Maple? I have been having some difficulty finding an explicit form for the algorithm on the net.

i have a laplace function. this function contains a integral. how can i use maple to find the fisth 10 terms of a maclaurin series. please, i really need help

using maple find out the sum of the follwing series: sum(n=1,infinity) 1/n^2; sum(n=1,infinity) (-1)^n+1/n^2; sum(n=1,infinity) 1/(2n-1)^2;

There's a discussion on generating cross-correlated sequences( http://www.mapleprimes.com/forum/generate-correlated-random-numbers), but how do I create a sequence of correlated random variables from an arbitrary distribution? How do I test a given time series (list,vector) for a possible autocorrelation (serial dependence) with maple? Thanks.

why when men talk about graphing newton's basins of attraction they always give complex exaples . For the real polynomials we have the same idea for example the polynomial : f(x) = x^3 + 2*x^2 - x -2 this has 3 real roots 1, -1, -2 and of course we have some intial x0 makes newton formula converge and other not so we will have basins. or for x^3 - 1 which has 3 mix of real and complex roots. Can you please help me in writing a maple program that create the graph of newton's basin for such real polynomials? and If you think that my idea is not correct can you please provide me with a maple program that create the basins for a complex polynomial so that I maybe can modify it for the real ones?.

hi let's say i want to plot sin(x) in excel i know that in excel i should type =Maple("plot(sin(x),x") now how to do that within vba i have already included the reference of maple within vba thank you

f(x)=x^2 expand in fourier series: a)by cosinuses on (0,pi) b)by sinuses on (0,pi) c)on (0,2pi)

Hi let's say i have a list like this one u:=[1,2,5] i want to know the max that is 5 in this case how to do that thank you

Hi guys, i created a procedure to produce the commutator lie bracket, for the lie algebra so basically commutator(x,y)=x&*y-y&*x where x and y are not commutative. But there is a problem when i add constants into the mix, like a*x, a is treated as a variable. So i wonder if within the simplify function, there is a way to set certain variables/constants to be commutative or to declare a variable as a constant variable. If more information is needed check down here I am attempting to output the results of a derivation map D so say we have 2 elements of the lie algebra, x and y, and L is spanned by x and y,

hi lets say i have 2 functions
h:=x->piecewise(x <= 5, x-1, x <= 7, 4, x <= 15, 18-2*x);
h1:=x->piecewise(x <= 3, -3/2+(3/2)*x, x <= 5, 3, x <= 15, 21/2-(3/2)*x);
i'm looking for, when h1(x)=h(x)
when i plot it
plot({h(x), h1(x)}, x, thickness = 3);
i can see 2 intersections
when i do
fsolve(h(x)=h1(x),x);
it returns me only one solution =1
is there any alternative to this
Normally i should have 2 solutions in the interval 1 until 10 , that are x1=1 and x2=4
thank you

is it possible ti split the sreen of maple thank you

Hi let's say i have 2 functions the first one is f :=x->[[1, 0], [3, 3], [5, 3], [7, 0]]; the second one is g :=x->[[1, 0], [5, 4], [7, 4], [9, 0]]; when i use plot({f(x),g(x)}); i can see the both functions and the intersection but I don't know how to calculate the intersection Can you help me please thank you .

I am new to Maple and still learning syntax, what I would like to do is to generate the elemets of GF(8) or to even how to multiply ploynomials modulo x^3 + x +1? Thanks for help any one can provide.

I have a Maple spreadsheet which I would like to plot some of the data from. Is there a simple way to select the columns of data for a 2 dimensional plot? The Maple commands below generate three columns of data and I would like to plot the first two columns. I have exported the file to Excel and generated a plot, but there should be a way to stay within Maple and do the same. Thank you for your help. > restart; > with(Spread); > beta_N := proc () local i, k, sol, beta, N_bar, Eq15, Eq16; CreateSpreadsheet(Eq15_16); i := 1; for k from .10 by 0.2e-1 to .5 do Eq15 := -2*k*cos(beta) = 1/sqrt(N_bar);
