Tests are learning, not just inspectors.

hi,

I'm currently proctoring for my univeristy math dept.  They ask me to put policy on testing website.  Please help me how to do that? thanks,

i have two quotes :

#1:

You confuse science with engineering, publication with patents. Intellectual property law does not recognize ownership of scientific truth. Your theory is true, or it isn't. You don't 'own' it. An apple does not need Isaac Newton's permission to fall to the ground. The primary protections for inventions are trade secret and patents. The primary protection for other intellectual property is copyright, and wise choices in how you use it and publish it.

Yesterday I attended a lecture by Fran Allen, as part of the "David R. Cheriton School of Computer Science, University of Waterloo, Distinguished Lecture Series".  Allen worked a IBM Research from 1957 to 2002, she was awarded the ACM's Turing Award in 2006.  Here is her biography from Wikipedia (let's hope it is accurate). 

Aside from some technical issues (why can't a room full of computer science professors and students successfully attach a laptop to a projector?) the talk was quite interesting.  There were two main sections, the first discussed Allen's career at IBM and the second was about the future of computer science.  Allen's work at IBM focused mostly on compilers and high performance computing.  She made a few interesting comments about the importance of high performance computing.  For example, one of the systems she worked on was designed and used to model the detonations of nuclear weapons.  The development of this system ended the need for the United Stated to perform actual test detonations.

Maplesoft has just released a collection of new engineering products, including MapleSim 3, the latest version of our physical modeling tool. It includes a new hydraulics library, more electrical machines and improved solvers which expand the scope of models it can handle. It also comes with a new project manager, more diagnostic tools, a 3-D visualization preview feature, and other improvements to the interface which reduce the development time. See What’s New in MapleSim 3 for details.

Good Afternoon,

Would anybody be kind to help me with the attached file. I have created procedures to calculate the Area, center of gravity , section modulus and moment of inertia of a cross section.

I'm testing the worksheet with an existing example from a text book, and the results are as follows

Area = 75*in2

Zxxtop = 119.219*in3

Zxxbott = 133.245*in3

Ixx = 629.212*in4

Zyyleft = 88.583*in3

Zyyright = 88.583*in3

Iyy = 442.917*in4

xbar = 4.722*in

ybar = 5.0*in

To evaluate some real integrals I use the 'assume' instruction to make sure all the quantities are real.  But Maple 12 can't seem to deduce the obvious inequalities from this - testing for them gives a FAIL result.  Here is a minimal example:

    assume(X,real, Y,real, w>0);

    is( (X+w)^2 + Y^2 >= 0);

Hi i am having difficulty converting a text file consisting of words into ascii code. using maple and vice versa.
I dont know how to.

My notepad text is  "(testing)" and i wanted maple to show me "testing"  in ascii code but i just dnt knw how to get it to do it.

Can someone please help me i would be very gratefull

Thank u

Hey there everybody. I've been working on the Project Euler (projecteuler.net) problems for a while now, using Maple or J to solve the problems. Some of the problems involve using palindromes or testing for palindromes. I know I can convert the number into a string, reverse it with StringTools, and then parse it back into a number, but that requires a lot of time and resources (the PE problems should be solved in under 1 minute).

As this question stands about the relationship between 'FunctionAdvisor' and 'convert', and it seems that 'convert' is not able to make the possible conversions listed by FunctionAdvisor(specialize, ...), the following command 'fas' (FunctionAdvisor Specialize) seems a posible workaround:

I was testing if Maple can prove/show limit(a*(1-F(a)), a=infinity,left)=0, where F(.) is a general cumulative distribution function. Though, I doubt Maple has the ability.  However, I come across with some other questions during the exploration:

1. how is maple exactly doing to find limit:
Let's first try a normal distribution case:
 

with(Statistics):
U := RandomVariable(Normal(s,t))  :
limit(CDF(U,x),x=infinity,left)  assuming t>0,t<infinity ;

I have been wondering about the reception of an independent patch Library for Maple.

I'll lay out a few ideas, and then maybe some criticism (or indifference) might follow.

I'm a bullet-point sort of person:

• sourceforge project with a few willing experts for vetting and gatekeeping of submissions.
• Patch .mla Library archive, going into /toolbox/Patch/lib/ so as to get picked up automatically by libname.
• Self-building, with...

The time for Easter eggs will soon be here.

And using LibraryTools to browse and poke about in Maple's .mla files can show a few undocumented items.

Here's one below, that's an interesting part of a package.
