BUG 1:

Severity: Medium-High

Reproduction #1:
>with(Student([Calculus1]));

IntTutor;

Try to enter "csc(x)^3" in "function", and let variable to be "x"

Click all steps, and watch the system freezes.
Or yo can click "Next Step", which won't change the integrand at all, you may click 100000000 times -- the program is in an infinite loop.

Hi! I'm a Maple Newbie trying to use the Maple Training Videos.

They all work fine except for two, under Algebra: "Solving Equations" and "Working with Matrices". Both start OK, then die a few seconds in.

I'm using Kubuntu Linux, but I really don't think that that is the problem, since all the other videos work fine.

Could someone try these for me to verify if they work for you?

Thanks in advance for any help.

Example 1  The region between y=x and y=x^2.

with(plots):

f:=x->x: g:=x->x^2:

F:=spacecurve([x,f(x),0],x=-0.2..1.2,color=blue, thickness=3):

G:=spacecurve([x,g(x),0],x=-0.2..1.2,color=red, thickness=3):

region:=plot3d([x,y,0],x=0..1,y=g(x)..f(x),color=grey, style=patchnogrid):

display(region,F,G,axes=normal,orientation=[270,0], scaling=constrained);

Example 2 The region between y=sin(x) and y=cos(x).

with(plots):

f:=x->sin(x): g:=x->cos(x):

F:=spacecurve([x,f(x),0], x=-0.5..6.5,color=blue,thickness=3):

G:=spacecurve([x,g(x),0], x=-0.5..6.5,color=red,thickness=3):

Region:=plot3d([x,y,0], x=0..6, y=g(x)..f(x), color=green,style=contour):

display(Region, F, G, axes=normal, orientation=[270,0],scaling=constrained);

Example 3  The region between x=y^2/2 and x=y^4/4-y^2/2.

with(plots):

f:=y->y^2/2: g:=y->y^4/4-y^2/2:

F:=spacecurve([f(y), y, 0], y=-0.1..2.1, color=blue, thickness=3):

G:=spacecurve([g(y), y, 0], y=-0.2..2.1, color=red, thickness=3):

Region:=plot3d([x, y, 0], y=0..2, x=g(y)..f(y), color=gray, style=patch,grid=[10,10]):

display(Region, F, G, axes=normal, orientation=[270,0], scaling=constrained);

Example 4  Bird’s eye view of Example 3 (Just change the orientation.)
with(plots):

f:=y->y^2/2: g:=y->y^4/4-y^2/2:

F:=spacecurve([f(y), y, 0], y=-0.1..2.1, color=blue, thickness=3):

G:=spacecurve([g(y), y, 0], y=-0.2..2.1, color=red, thickness=3):

Region:=plot3d([x, y, 0], y=0..2, x=g(y)..f(y), color=gray, style=patch,grid=[10,10]):

display(Region, F, G, axes=normal, orientation=[300,55], scaling=constrained);

Could you solve this problem?

Hey.

If you go to url, http://www.fcet.staffs.ac.uk/blb1/FirstYearEng.html, you shall see four maple worksheets in XML format.

My issues is that i can open them all but the last one, Geometry?

Can any one suggest a reason why i keep getting an error when trying to open this sheet? Does it do if for you?

If i can be cheaky, If some one can open it, can they save it in a Maple worksheet and send it over to me please?

Thanks for any help

What is the following equation about?

(a+b^n)/n = x

It has too many unknowns.  There seem to be too many trivial solutions: a=b=n=1, x=2 or a=1, b=2, n=3, x=3 or a=2, b=2, n=2, x=3 and on and on.  Why would anyone think that this has anything to do with the existance of God?

The following is from en.wikipedia.org/wiki/Leonhard_Euler

There is a famous anecdote inspired by Euler's...

I use Maple primarily in a Unix text window (TTY or "command-line" Maple), so I am used to seeing common subexpression labeling in the output of my computations. However, in Maple 11, GUI users don't see subexpression labeling by default.  I'll begin by talking about subexpression labeling as it appears in TTY Maple, then I'll talk about it in the GUI.

For starters lets look at an example in which a single subexpression is labeled:

As many here know, Gaston Gonnet is a co-founder of Maple.  SIAM, in its History of Numerical Analysis and Scientific Computing project, has now published a very long interview with Gaston.  For those who like a good yarn, as well as details of the history of Maple and Maplesoft, it makes for fascinating reading.

My favourite quotes are:

I have just completed a new update to the site that allows me to disable the new WYSYWIG editor for specific users. Users cannot make this change themselves at the moment, an administrator must make the change for them.

If you would like the editor disabled, please use the contact form to send me a message.

they seem to have disappeared!

Something strange happens when you try to plot this:

implicitplot([y = 1/18*(3*x+1)^2/x], x = 1/4 .. 1/2, y = 0..10);

If you change the y range so that it is, say 1, the wabbles in the function become smaller, but they are still their.

Why the wables?  I am using Maple 9.
 

For the past few days I was unable to login using either my mapleprimes or maplesoft account information.

Was this happening to anyone else during the recent mapleprimes changes ?

f1 := proc(m, S::set) map(s->`if`(s={1},{m}, s),S); end:

f1(X, {{1}, {2}}); differs from inlined version of the same

f2 := proc(m, S::set) option inline; map(s->`if`(s={1},{m}, s),S); end:

f2(X, {{1}, {2}}); The first non-inlined version f1 is be my opinion correct, but what about the inlined f2?

I am still missing the implementation of the pre and code tags in the new editor. As the editor works now, having to switch back and forth between WYSIWYG view and source view, I feel it puts a higher workload on me than its predecessor did.

Also, I am missing a properly working maple tag: the browser seems to show only a fraction of the image intended. Because of this, for a couple of posts, now, I have left out informative Maple output. That can hardly be the way this site is supposed to work.
