Hi there.
How are you?
I feel sorry since I purchased Maple. Let see if you would agree.
First of all, it is inferior to the Ti-89 in some aspects.
I have tried to use Maple 11.02 to solve the problems:
(sqrt(2)+1)^x+(sqrt(2)-1)^x = 3;
And Maple 11.02 fail to solve, then I tried to solve numerically, it missed one solution.
There must be 2 solutions for the problem above and Maple missed 1, the Ti-89 beats it hand down.
The second problem I tried was:
int(sqrt(sin(x))/(sqrt(sin(x))+sqrt(cos(x))), x = 0 .. (1/2)*Pi);
and Maple even stuck... The Ti-89 return answer correctly within about 20 secs.
Does anyone know how to get the
openmaple api to compile in the
presence of the package com.webobjects .foundation?
This week I made up an exam using Maple where I didn't want the input to be visible. I used View|Show/Hide to accomplish that. This worked alright within a short time frame. I could save the file with the input hidden, and then I could reload the file and, upon re-checking input to show, all the input would re-appear. However, when I let the file sit for a few days and then tried to re-show the input today, all the input in each execution group was condensed into one line with '?'.
This sure seems like a Maple bug to me. Does anyone have any other ideas about how this could happen? Or how one might recover the input?
Just a friendly reminder,
Regards,

How can I write an algorithm in maple that gives me a lisft of the Fibonacci polynomies between two numbers using the recursion:
F1(x) = 1
F2(x) = x
Fn+1(x) = x*Fn(x) + Fn−1(x)
if anyone knows please help me!!
And the same question(gettin a list between two numbers) using the sum:
sum(binomial(n-j-1,j)*x^(n-2j-1))),j=0..floor((n-1)/2)
Please help...
Thanks =D

Have you ever plotted a function in Maple and then found that the range you plotted it on wasn't really what you wanted? You can always re-execute the command, of course, but that means working out exactly what the range is for that interesting feature you want to investigate, and if you've made changes to the plot those will be lost. However Maple has the ability to zoom in on a plot interactively, without re-executing the command.
The Axis Properties dialog lets you change the range numerically, but you can also do so using the mouse. Go to the plot toolbar and click on the Scale plot axes button (it looks like a red ball with an arrow). If you have an animation you will need to click on the word "plot" above the toolbar to switch from animation to plot toolbar. Now put the mouse in the middle of the plot and drag it. Dragging it down will zoom out, increasing the range; dragging it up will zoom in. The Translate plot axes button lets you 'pan' i.e. move the centre of the axis ranges without changing the range size.

How can I write a recursive algorithm on maple wich gives me the fibonacci polinomies knowing that:
F1(x) = 1
F2(x) = x
Fn+1(x) = xFn(x) + Fn−1(x), n = 2, 3, ...
help me please!!!

To those who are interested:
New version of
FourierTrigSeries package was released. This release fixes a bug in
ExploreFourierSeriesCoefficients procedure.
FourierTrigSeries package provides new data structure for the representation of trigonometric series and also several procedures to manipulate with trigonometric series and to compute Fourier series.
Visit the
homepage and see some examples. Try also the online Fourier series calculator.
I am fooling around a bit with
dismantle and
ToInert. In the light of the passage "For the exact internal representation, see dismantle," in the help page on
ToInert, I am surprised to see that
dismantle does not provide any information concerning the entries of a given matrix, as do
ToInert:
expr := Matrix(2,2,(i,j) -> m||i||j):
dismantle(expr);
ToInert(expr);
RTABLE(11): 4 [1..2, 1..2]

Why am I getting this strange result?
evalb(sin(1)/cos(1) - tan(1) = 0) gives false
but
evalf(sin(1)/cos(1) - tan(1)) gives 0
so the evalb should give true.
I originally got a result of
(sin(x)^3) / (cos(x)^3)
in a calculation and asked maple to simplify, expecting tan(x)^3. This led to my investigation of my assumptions about this trig identity. However, for the specific example above, Maple seems to be flat out wrong. Also the boolean returns true if the arg is changed to 0.
If I create a question using the Question Designer, and I insert a Response Area of the List type, and the text of my list items contain multiple consecutive spaces, this will cause problems in the assignments that include this question...
In the assignment, if I select an answer for this question using the drop-down list and then I navigate to another question and then return to this question, my answer will not be selected. And if I then navigate away from this question again without reselecting my answer, MapleTA will not record an answer for this question and so it will be marked incorrect.
MapleTA currently restricts feedback in only one sense -- you can prevent access to feedback until AFTER a specified date.
I provide MapleTA support for the University of Nebraska-Lincoln, and an instructor has come to me with what seems like a reasonable desire -- that unfortunately does not seem possible at this point.
He is creating proctored exams. Students take proctored exams on campus in our testing center, which is staffed by proctors. The instructor wants his students to view the results of their exams in this proctored setting so that they can mentally take note of which questions they got wrong and which questions they got right, but cannot produce a hard copy of the exam. And he doesn't want students to be able to go back to their dorm rooms and view the exam.
