what is annoying about CAS
Es geht um
what I have (dp(...) is a user def function calling p(...) a user def Function)
The example file holds a line with
(10) A2:=Sequence(p(kk,XY(kk-1,1))=XY(kk-1,2),kk,1,n )
produces equations as wanted. But some lines later (12)
(**) Sequence((dp(kk,XY(kk,1)) = dp(kk+1,XY(kk,1))) ,kk,1,n-1)
Sequence((dp(kk,XY(kk,1)) - dp(kk+1,XY(kk,1))) ,kk,1,n-1)
but the answer is Some thing went wrong...
why do simple relationships like (**) fail so often?
I spend a lot of time to find a workaround
(12) A4:=Sequence(dp(kk,XY(kk,1)) ,kk,1,n-1)-Sequence(dp(kk+1,XY(kk,1)),kk,1,n-1)
but actually I need an equation with left and right side.
so i immediately have the next workaround in view because the right side of the equation is missing
Any reason why the nested function dp( ) cannot used as p( )
