Question: Concern analog signals in electrical engineering, which are continuous functions f(t), where t is time. To digitize the signal, we sample f(t) every Δt to form the sequence sn = f(nΔt). For example, if f(t) = sin t with t in seconds, sampling f every 1/10 second produces the sequence sin(1/10), sin(2/10), sin(3/10),.... Give the first 6 terms of a sampling of the signal every Δt seconds.
f(t) = cos5t, Δt = 0.1
