(a) Express each of the following as a single cosine function: 5 sin 300t, 1.95 sin (t
Chapter 10, Problem 2(choose chapter or problem)
(a) Express each of the following as a single cosine function: \(5\ \sin\ 300t\), \(1.95\ \sin\ (\pi t - 92^{\circ})\), \(2.7\ \sin\ (50t + 5^{\circ}) - 10\ \cos\ 50t\). (b) Express each of the following as a single sine function: \(66\ \cos\ (9t - 10^{\circ})\), \(4.15\ \cos\ 10t\), \(10\ \cos\ (100t - 9^{\circ}) + 10\ \sin\ (100t + 19^{\circ})\).
