Hi all, I am new with maple! I want know if maple has the some tools to create a GUI as matlab. Is there a function "patch" as matlab? Regards

Hello If we have an integral of say two functions f(x) & g(x) and we know one function and the solution for the integral. Can we find out the other function using Maple. Could anyone guide me on this. Regards S

p >Hello. I'm still kind of new to the practice of using a computer program to manipulate equations. I knew that one way to define an ellipse is as the locus of points P such that for 2 fixed points F1 and F2 the sum PF1 + PF2 is constant. I also know that in Cartesian coordinates, we get a formula of the form Ax2 + By2 = 1. If we set up our coordinate system such that F1 and F2 are on the x axis each a distance c from the origin and the maximum width of the ellipse is 2a, let's try to figure out A and B using MAPLE.

define(h,'orderless',h(1,2)=3); works as I would expect and h(1,2) and h(2,1) evaluate to 3. define(h,'orderless',h(2,1)=3); gives both h(1,2) and h(2,1) evaluating just to h(1,2). I suspect this is a bug since replacing 1,2 by a,b or by b,a it works as I would expect. Is this (another) fundamental bug or have I misunderstood something? I'd be interested in any comments.

I have to press 'login' twice to get the navigation bar on the LHS to show me as 'logged in'. This has been happening to me for about a month now, and it is irritating. I am using Firefox 1.5.0.8 on Windows XP.

I wish to know if there is way to plot the following functions: x1=X1+X2*gamma(t) x2=X2 and x1=alpha*cons(theta)*X1-beta*sin(theta)*X2+gamma x2=alpha*sin(theta)*X1-beta*cos(theta)*X2+gamma where in the second one alpha, beta. and gamma are constants. many thanks, A.

Maplesoft.com recently posted a new user story that describes how Maple was used by a German company that develops, produces, and distributes towing kite wind propulsion systems for modern means of sea travel and transportation.

Here is a quote from the company:

“SkySails is grateful to Maplesoft, because Maple saved us a lot of time. Using Maple was very easy and quick. The computations we used are probably very basic for Maple, but they were extremely effective for SkySails. When testing the simulator, the correctness of the mathematical model is crucial. With Maple, there was nothing to worry about!”

The following equation cannot be plotted correctly in the usual 3 dimensional plot with Cartesian coordinates. eq := (x^2+y^2+z^2-1)^3 - x^2*z*3 - y^2*z^3 = 0; Either a 3 dimensional implicit plot, or a spherical coordinates plot is needed. What surprised me was how long Maple 10.06 took to produce the latter with very roughly the same amount of detail as the former: 454 s versus 0.7 s. It seems as though one should always prefer the implicit plot to the spherical plot if the 3 dimensional Cartesian plot fails. I would be grateful for any thoughts about this and any improvements to the code below. (Apologies for not posting the worksheet – I think that File Manager might object to its 10MB size!)

Hi, I am Sripad from INDIA. Here is a query on Maple. If I give Integration of log(cotx)+log(tanx), then Maple is giving me an answer in terms of dilog and I. But actually it should be a constant. Could someone help me, how it can be done in Maple. Regards Sripad

Sequence A125033 in the OEIS submitted by Paul D. Hanna and Richard J. Mathar, is defined as Number of labeled nodes in generation n of a rooted tree where a node with label k has k child nodes with distinct labels, such that each child node is assigned the least unused label in the path that leads back to the root node with label '1'.

I have installed Maple10 on Windows XP, but when I execute "maplew.exe", Maple doesnt start. I can only start the classic Worksheet. Can you help me please?

I'm contemplating purchasing one of the manuals available from the maplesoft website. Has anyone here bought and used any of these books ? Does anyone have any opinions, or reviews they can share with me ? I'm thinking of buying the advanced programming or combined beginning and advanced programming PDF book. Thanks, Dan

I am taking a class where we have to solve second order differential equations (symbolically) for spherical and cylindrical coordinates. The equations are sometimes written D(r^2*D(f(r)) (all are differented with respect to r, but it has r^2 between first and second differential. Can Maple solve something in that form?

New York-

A public school teacher was arrested today at J.F.K. International Airport as he attempted to board a flight while in possession of a ruler, protractor, a set square, a slide rule and a calculator. At a morning press conference, Attorney General Alberto Gonzales said he believes the man is a member of the notorious Al-gebra movement. He did not identify the man, who has been charged by the FBI with carrying weapons of math instruction.

"Al-gebra is a problem for us," Gonzales said. "They desire solutions by means and extremes and sometimes go off on tangents in search of absolute values. They use secret code names like 'x' and 'y' and refer to themselves as 'unknowns', but we have determined they belong to a common denominator of the axis of medieval with coordinates in every country. As the Greek philanderer Isosceles used to say, 'There are 3 sides to every triangle.'"

When asked to comment on the arrest, President Bush said, "If G-d had wanted us to have better weapons of math instruction, He would have given us more fingers and toes."

White House aides told reporters they could not recall a more intelligent or profound statement by the President.
