Solve the problem.On a Touch-Tone phone, each button produces a unique sound. The sound produced is the sum of two tones, given by y = sin (2?lt) and y = sin (2?ht)where l and h are the low and high frequencies (cycles per second) shown on the illustration.
The sound produced is thus given by y = sin (2?lt) + sin (2?ht)Write the sound emitted by touching the 2 key as a product of sines and cosines.
A. y = 2 sin(780?t) cos(2174?t) B. y = 2 sin(2033?t) cos(639?t) C. y = 2 sin(2174?t) cos(780?t) D. y = 2 sin(639?t) cos(2033?t)
