# I'm trying to define forward difference operator in maxima. Forward
difference op is defined such that: delta y(x) = y(x+h) - y(x)
# I wrote:
# This works fine for the first order. But when I tried to apply delta^2 to
any function, it gives an error:
y evaluates to sin(x + h) - sin(x)
Improper name or value in functional position.
-- an error. To debug this try debugmode(true);
# Do you have any suggestions? Thanks in advance.
