Hello,

I just received and installed Maple 11.  (Maplesoft wouldn't sell me the student version, but I learned they have an unadvertised Home User version which is reasonable.  You have to call on the phone to order it.)  So far it's working well, but I can't figure out how to get an exact (symbolic) solution to a quartic with integer coefficients.

I'm asking Maple for simple things only, yet still (5 years later) I get nothing.

I'm creating 3 contour plots for potential functions in 3 bordering regions of 3-space,

because a continuous potential function isn't possible to define. 

After an entire worksheet worth of variable definitions and series expansions, i say simply:

CPA:=contourplot3d(VI(a,b,c,d,e)......)

CPB:=contourplot3d(VII(a,b,c,d,e)......)

CPC:=contourplot3d(VIII(a,b,c,d,e).......)

I posed an integration problem and Maple solved it so easily I decided I would like to get Maple.  I'm waiting to hear whether Maplesoft will sell me the student version.  While I'm waiting, I would like to ask this group a question I've always had about systems like Maple.  I will start by posing a problem:

Let C be a unit circle and let P be a point on C.  Draw a bigger circle B with P as center which crosses C at two diametrically opposed points of C.  What is the area of the crescent-shaped region inside C and outside B?

Hello Everyone:

I used to receive emails each time when a comment/reply was made to my questions on mapleprimes. Very convenient. Now this service either stopped to exist or something else, as I receive nothing. Can it be resumed somehow? Thanks.

I am thinking about buying Maple, but I would like to know how it does with the following problem:

f(x):=log(2-cos(x)+sqrt(3+cos(x)*(cos(x)-4))) ;
r(n,p):=(1/%pi)*integrate((1-exp(-abs(n)*f(x))*cos(p*x))/sinh(f(x)),x,0,%pi) ;
r(1,3) ;

These are Maxima commands--let me know if it is not clear what they are doing.  I am wondering if someone with Maple could translate these commands into Maple-ese and try them. (Maxima just gives up on this integral.)

The following give very different answers.

> evalf( int( ln(2+2*cos(t)^2+cos(t)^4), t = 0 .. Pi));

   -8.710344354+19.73920881*I;

> evalf( Int( ln(2+2*cos(t)^2+cos(t)^4), t = 0 .. Pi));

Hello to All,

I am just in testing process of new version Mechanics of Materials 2.0 ToolBox.

Some of Maple pictures are so good that I decided to put here one from them.

What a great Maple...

Sorry for my some immodesty...

Hello All,

     In Document Mode, I entered the following 2 lines and observed 2 different behaviors from Maple 10,

       sin(4.5)=-.9775301177         I can NOT enter anything after ..177, the output.  Here = is ctrl+=.

I have come across an integral that behaves badly/oddly for specific forms of the limits.

The integral is

Hello,

  New to Maplesoft so on a bit of an exploration here.  I see lots of applications, samples, worksheets, demos, etc., but is anyone aware of Maple packages/efforts that are full/thorough complements to any of the popular HS math textbooks in use (any/all grade levels)?  By full complement I mean Maple exercises/explorations/demos that, on a chapter by chapter basis, augment the specific topics/exercises of an entire text book.  I know any teacher can work up a sheet at anytime; I'm looking for prepackaged, ready to load and go for text books.

Hello maple users/support!

How can I access local variables of a module without having to write set_X() get_X() functions for all variables I want to read/write to?

thx for your help,

           sepp.

First, consider the following two analogous codes:

restart:
x := setattribute({1,2},parity):
x,attributes(x);

restart:
x := setattribute([1,2],parity):
x,attributes(x);

Both in Maple 9.5 and Maple 11 they produce the expected output; {1, 2}, parity and [1, 2], parity, respectively. Next, consider the following two analogous codes:

I need to find an example of a function of one variable that has an antiderivative that can be expressed very simply in terms of fuctions that a 1st-year calculus student would know, but int (command name in maple) can't find an antiderivative.

Hint: Start with the antiderivative F(x), and get f(x) by differentiating it and simplifying. You might try something involving a few square roots and logarithms or exponentials or trigonometric functions.
