A tuning fork is held a certain distance from your ears and struck. Your eardrums' vibrations after t seconds are given by
p = 8 sin 2t When a second tuning fork is struck, the formula p = 2 sin (21+ I) describes the effects of the sound on the
eardrums' vibrations The total vibrations are given by p = 8 sin 2t + 2 sin (2t + r). Complete parts (a) (b)
(a) Simplify p, the total vibrations, to a single term containing the sine.
