Could someone give me solution for the question below maybe only a and b if not all of them , 

tahnks.

Consider the operation L on functions f(t) under the definition
d² f
dt²
df
L(f(t)) = f(t) + +
dt
That is, we can express L as:
d
dt dt²
L:=1+ +
(a) Compute L(t³ – t²).
(b) Express L(tan(t)) in terms of cos(t) and sin(t).
(c) Compute L(ect) and express in factorised form.
(d) For what values c ER does L(ect) = ect?
