@vv 

and it possible to obtain D[1](f)(x,y) = piecewise(x=0 and y=0, 0, ....)?

@vv 

Thanks for your reply, it is correct. But i I was wondering if it was possible to do it directly, or rather if maple noticed the change of law and then calculated the derivative directly using the definition

@Preben Alsholm 

thanks a lot

Dear Preben, i have used your commnda but maple2016 reply

@Kitonum 

good morning, i would like to do the same but in 3d, namely i would like to fill

there is something analogous for 3d?

thanks, anna rita

@Carl Love 

thank you for your reply, in this way i can have a look on the faces of the cube, but i am not able to visualize if in the interior there are max or min.

@annarita 

so, do you know if there is a possibility to color the whole cube in maple 7 using a functions?

@annarita 

thank you , i see now that colorscheme works on maple 18!

@Carl Love 

maple reply me with an error: unexpected option colorscheme

@tomleslie 

 

restart; plots[display]*(plottools[cuboid]*([0, 0, 0], [1, 1, 1]), transparency = .7, colorscheme = ["xyzcoloring", proc (x, y, z) options operator, arrow; x^2+y^2-z^2 end proc])

 

thank you for your reply, i have copied your command but there is again a problem since the plot does not appear again

the system gives only the command in blue. today i'm also not able to copy and paste here... firefox said me that this is not possible....

 

@Preben Alsholm 

thanks for your help!
