Solve the problem.A product of two oscillations with different frequencies such as f(t) = sin(10t) sin(t)is important in acoustics. The result is an oscillation with "oscillating amplitude." src="https://sciemce.com/media/4/ppg__tttt0506191043__f1q58g4.jpg" alt="" style="vertical-align: -4.0px;" /> last two functions constitute an "envelope" for the function g(t). For certain values of t, the two cosine functions in g(t) cancel each other out and near-silence occurs; between these values, the two functions combine in varying degrees. The phenomenon is known (and heard) as "beats." For what values of t do the functions cancel each other?
What will be an ideal response?
the product f(t) of the two oscillations as a sum of two cosines and call it g(t).
a graphing utility, graph the function g(t) on the interval 0 ? t ? 2?.
the same system as your graph, graph y = sin t and y = -sin t.
