Question

Question: Make a carefully labeled sketch for each of the following functions.

(a) Sketch case θ for values of 0 in the range 0 ≤ θ ≤ 6π.

(b) Sketch cos (0.2πt) for values of t such that three periods of the function are shown.

(c) Sketch cos (2πt/T₀) for values of t such that duce periods of the function are shown. Label the horizontal axis in terms of the parameter T0.

(d) Sketch cos (2πt/T₀ + π/2) for values of t such that three periods of the function are shown.
