Hello,
I created an operator:
op[x_] = (D[#, x] + 3 x #) &
I can apply this to a function f[x] and create a new function as follows:
f1[x_] = op[x] [f[x]]
My question is: how can I apply the operator multiple times to f[x] in a single statement? I'd like to do this a large number of times, so I don't want to use a large number of brackets.
Thanks, Joe
