Satya's back (try this!!)

SOLN:
g(x+1) + g(x-1) = g(x)
g(x+2) + g(x) = g(x+1)

adding both,
g(x+2) + g(x-1) = 0 = g(x-1) + g(x-4)
=>g(x+2) = g(x-4)
=> period = 6

way to go! Asish..good job..correct the 4th line

substituite g(x) =cos (Ï€x3)

good to find a substitute in case of exam

but its neither too long nor too difficult.....

anywyays good one

its not exactly a tukka

its a charateric function of this recursion !

generating polynomials ? rit

yeah edited :)
