MaplePrimes Questions

hello all ... peculiar problem here ... please help the expression is true that 1/n(n+1) = 1/n-1/(n+1) since 1 = n + 1 - n gives 1/n = (n+1)/n - 1 Is there a way to demonstrate this identity in Maple ? ? I cant find any trick with "expand" or such that works. This impact is also seen when evaluating ... the following ... sum(1/n-1/(n+1), n = 1 .. infinity) = 1; = print(`output redirected...`); i get the proper answer of 1 but no answer with :::
I know maple has two functions max and min to compute the maximum and minimum of some arguments. But I have a list,such as l:=[1,2,3]; when I use the maple function min,I need to write: min(l[1],l[2],l[3]); How can I simplify the expression? If l is list with too many items,how to use min to calculate the minimum?
I need to make a list of 12 random integers from 0 to 1. Take the sum of those values and subtract 6. I have that part....now the part I don't have is how do I run that 10^6 times and keep track of my values? with(RandomTools): with(stats): with(ListTools); > L := seq(Generate(integer(range = 0 .. 1)), i = 1 .. 12); 1, 1, 1, 1, 1, 1, 1, 0, 0, 1, 1, 0 > > G := add(i^2, i = L); 9 > Z = G-6; Z = 3 That is my program so far. Any help is appreciated.
Does anyone know if there is a way to obtain the coordinates of an ordered pair on a graph? I see that Maple states the ordered pair your cursor is currently situated at, but what I want is to 'grab' these coordinates and use them in other calculations. Essentially what I want is a Maple command similar to ginput on Matlab. Thanks.
> plot([(12-2x)^(0.5)], x=-10..10); Error, missing operator or `;` this line looks right to me but i keep getting that error in maple. i have also tried: > plot((12-2x)^(0.5), x=-10..10); does anyone have any ideas how i can fix this? any help would be great thanks
On Maple 11 Modern Version: If I have two parametric curves, say y = 4t + t^4 and x = 5t - 7t^2 how can I plot an equation such as (y'') * (x') + (3x'') with ' being differential and '' being second differential. I have tried it in numerous ways but get the following error message - "Warning, unable to evaluate the functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct". I have been trying to plot for t=-1..1. Thanks
Several weeks ago I submitted a request titled "Plot This! - Elliptic Integrals", which Dr. Robert Israel responded to with the following code which successfully plots the relationship of two variables, beta and k, over the range of interest. > with(plots); Digits := 15; > implicitplot(2*EllipticE(sin(beta), k)-EllipticF(sin(beta), k) = tan(beta)*sqrt(1-k^2*sin(beta)^2), k = 0 .. .99, beta = 3.5 .. 5.5, view = [0 .. 1, 3.5 .. 5.5]); However, the plot indicates that for the range of k=0..0.99, beta is approximately equal to 4.77 radians (273 degrees), whereas the paper that I am researching indicates a value of beta equal to 257 degrees 28 minutes. I have attached worksheet that includes the commands provided by Dr. Israel for information.
I'm looking for some examples of how Maple is being used by others to solve good, old-fashioned freshman physics homework problems. I have been getting the job done but my command of the program is so limited that I wind up using it like just an old graphing calculator. I'd really like to see how other, more advanced users are using it. Any suggestions?
Hello everybody, I hope some of you have experience with multivariate Ore polynomials in Maple and will be able to answer the title question. So far I've needed only univariate Ore polynomials, used the OreTools package for them and have been very satisfied with it. However, now I've come across a problem that needs to employ multivariate ones - therefore I am forced to try the Ore_algebra package, which should make computations with multivariate Ore polynomials possible (as far as I know, OreTools cannot handle multivariate Ore polynomials - or am I wrong? I wish I was) And here comes my trouble! Not only that I am not able to solve my multivariate problem with Ore_algebra, I don't even know how to do simple calculations (which can be so easily performed with OreTools) using Ore_algebra.
Hi everyone, I m a beginner with maple, so please, be patient with me! I m trying to use some complex algebra in maple. In particular, I want to define a function f(r,z) and I want to impose it to be REAL. So I thought, let's first impose the variables to be real(I'm using Maple 10, so I write everything as if I was in a document, ok?): assume(r,real) assume(z,real) after I have done this, I define the function, using the appropriate f(x,y) button in the toolbar: F:=f(r,z) and I impose it to be real: assume(F, real) but for some reason this does not work. Anyone knows why? The reason why I need to impose the function to be real is that F will be later multiplied by exp(Iz) to form a complex number.
Here is a technique which I need to do over and over and over in Maple. I am currently writing a research paper for the International Journal of Mathematics and Mathematical Sciences. I need to get this example out as soon as possible. Suppose I want to create a matrix where the (i,j) entry is the polynomial x^i + (x+1)^j whatever the entry is.. it doesn't matter. Point is that the entry depends upon the row i and column j How can I create and fill such a matrix? My matrices a slightly more complicated, involving entries such as diff(x^i + (x+1)^j,x) where it is actually easier
Hello, I am just learning how to use Maple and only have Maple 9.5. I am attempting to read in a single column of data from a pre-made txt file into Maple but I am having difficulty. For some reason Maple states that it cannot find the file that I am pointing it to. This was what I wrote... >restart; >RD:=readdata("c:\temp\test.txt"); I tried using " instead of ' and it gave me an error message as well. Any ideas what the problem might be? Thanks.
Two matrices U and H are related by U = exp(i*a*H), where I assume a is a real constant, and i denotes the square root of -1. (a): If H is Hermitian, show that U is unitary. (b): If U is unitary, show that H is Hermitian. (H is independent of a.) Any advice or hints greatly appreciated, v/r, This is from the title "Mathematical Methods for Physicists" by Arfken and Weber. 6th ed. (section 3.4)
I've got two procedures set up that work, but I know there have to be better ways to accomplish the same goals. First, I've got a procedure that finds to how many digits two floats (a and b) agree. I had tried a few methods of examining the SFloatMantissa and SFloatExponent of the difference, but those methods would fail in unpredictable ways. My current method explodes the floats into lists and compares every entry in a for loop. The example below is basically the heart of my procedure (I do take into consideration things like the location of the decimal and trailing zeros):
I already was explained that with maple is difficult to obtain the CDF of CharacteristicFunction of Z= (y1)^(1/2)+log((40-y2)*(80+2*y2-3y1))? where y1 = min(s1+X1, s2+X2) y2 = min(s3+X1, s4+X2) and Xi is IID uniforme[-1,1]. But .. could someone help me with some bibliographical references to deal with my problem?. It would help me to understand better and if possible to modify my formulation. Thanks in advance! Jean (I am using maple 10 under windows).
