Hello,
I'm having some problems with a recursive function.
Could somebody please help me by telling me how I
should enter such a function?
tia,
This is what I've done so far:
f[n_]:=Sin[Pi*n*(0.05+(0.0005*n))]
y[n_]:=1.5*y[n-1]-0.85*y[n-2]+f[n]
I'm trying to Plot[y[n],{n,0,320}] but that gives me
an error: $RecursionLimit::reclim: Recursion depth of 256 exceeded.
btw, is there an option to fill the area under the sine?
