In electrical engineering, a continuous function like $f(t) = \sin t$, where $t$ is in seconds, is referred to as an analog signal. To digitize the signal, we sample $f(t)$ every $\Delta t$ seconds to form the sequence $s_n = f(n\Delta t)$. For example, sampling $f$ every 1/10 second produces the sequence $\sin(1/10)$, $\sin(2/10)$, $\sin(3/10)$,...

Suppose that the analog signal is given by Give the first 6 terms of a sampling of the signal every $\Delta t = 1.5$ seconds:
