\sin(2\pi t)$

Here are the detailed answers to the questions in the picture.

1a)

Continuous-time vs discrete-time signals:
- Definition: A continuous-time signal $x(t)$ is defined for all real values of time $t$ . A discrete-time signal $x[n]$ is defined only for integer values of time $n$ .
- Mathematical Example:
  - Continuous-time: $x(t) = \sin(2\pi t)$
  - Discrete-time: $x[n] = \cos(\pi n/4)$
- Sketch:
  - Continuous-time: A smooth, unbroken curve.
  - Discrete-time:
