ASK YOUR TEACHER DETAILS -/3.22 Points) MY NOTES SPRECALC7 7.2.076. Two identical tuning forks are struck, one a fraction of a second after the other. The sounds produced are modeled by {(t) = sin(at) and (20) sin(wt + a). The two sound waves interfere to produce a single sound modeled by the sum of these functions. f(t) = sin(w +sin(t + a) VU (a) Find values for A and B such that can be written in the form A Siwt) B cos A= B (b) Suppose that Chio and a = 1/3. Find constantsk and so that yksincot). k= 6 Need Help? Read it Watch it Submit
