I try to use piecewise function to select the roots when a changes to (-0.5,0.5) , but hindered by some errors.

Can you help me?

Thank you very much!

Best regards!

Thank you very much, Mr. Preben Alsholm. I forget the other root. I will try to convert a to time t , which used to control the animation. I think it is not a easy task.

Best regards!

I can't help myself saying that it is a really wonderful solution by using arc length integral to derive the parametric representation of the curve parallel to y=x^2.

Best regards.

Longing for more magic gems. They are of educational. Very magic.

Best regards!

Thank you very much! Following your instruction, I change x[0] to x0, then the error disappeared.

Best regards!

 

PS: It is my fault to substitute a:=0 for x[0]:=0 in the Gem 11.

He denied and saied that the number I phoned was a home phone number in one neighborhood. I have try my best, but nothing useful information obtained.

I agree with you for setting up some security rules on the site.

@Will  Thank you very much for sharing this package, I feel this package is very useful and convenient for ploting. But after copying GridDisplay.lib and GridDisplay.ind to my maple library folder, c:\maple\lib, and running the examples, nothing returned. Then I find there are two folders named "lib" in maple14, one locates in c:\maple\lib , the other one locates in c:\maple\maple14\lib .

Can you tell me which folder I should use? I try both of them, but alway get nothing.

Best regards.

I will phone the number tomorrow, because it is just midnight this time.

 

PS: I phone the number this morning, 86-021-2133698956, but nobody answer the phone. The other number, 86-5943910000 is a wrong number, even I add zone code of Putin, namely, 86-0597-5943910000 doesn't exist. Then I send an email to 23dre@21cn.com and find this email address doesn't exist.

I will phone the number 86-021-2133698956 in the next few days.

The second link is a personal web(blog) similar to facebook, but very unpopular in China. I have leave a message in Chinese to remind s/he don't attack mapleprimes anymore. If maplesoft can provide the telephone number about that company, I can phone them.

After browsing the website www.ptidc.com , I find it is a company which provides server leases. Now maple is much stronger than before, and more competitive, especially after releasing maplesim, the customers of maple/maplesim are more and more. I think some guy is running undesirable competition to destory the corporate image of maplesoft.

I am also very angry about the spam attack, and feel ashamed of the server provider. This will also destory the reputation of China.
