2. (5 points) Consider the DT signal x[n] given by x[n] = −n²u[n] Characterize the signal as periodic/aperiodic (1 pt), even/odd/neither even nor odd (1 pt), and en- ergy/power/neither energy nor power (3 pts). You must substitute the signal into the energy and power equations and must make a well reasoned argument.

Write one line of MATLAB code that will generate values of the sinusoid x1 (t) above by using the complex- amplitude representation: x1(t) = Re{Xejwt} Use appropriate constants for X and w.

4) The function sin x (which you may remember from Calculus 1 limits) is important in signal processing and electrical engineering, and is known as the "sinc" function, often abbreviated as just sinc(x). Find § sinc(x) dx. Then, approximate ſ sinc(x) dx using the first five terms of the appropriate series.
