These are questions asked by casperyc

I am not sure how/why, but here is the worksheet.


The function evalutes fine and can be used for sequence. But it does not seem to be working with plot or Maximize.

V is assumed to between 0 and 1.

Need some help.





How do I delete me "Current profile picture"?

I just want to have a look what my "default" picture would look like now?

it seems that I can only update with a new picture, but can never go back to the default setting.






Does not work.





But with some effect,



Could this possibly be improved in the next release?

In this file, I tried my best to solve the pde. But the answer is still rather non-informative. I need some help to simplify it.

I did notice that my Maple might need reinstallation, due to a "bug" in the 18.02 update.


My ultimate aim is try to use some similar techniques to solve this,, which has a similar type pde.


The standard pdsolve(pde) would just not work.



I used the same file in Maple 17 on a differnt Machine, which can be solved by pdsolve. So I guess it's just that  the 18.02 update package is broken itself. I have tried to uninstall and reinstall twice.






In this document, I think that is the relevent section. But I couldnt understand it.


I want something like this





>plot(sin(x),color=ABC); # error

>plot(sin(x),color=CBA);# error

optional, but works fine within a given sets of choices.


How do I write a procedure like that?
