Solve the problem.In a particular situation, the pressure, P, exerted on a person's eardrum at a distance of 8 feet from the source is given by the function: P(t) = 
cos (2n? - ct) , where n is a positive integer. Use the difference identity for cosine to simplify P in this situation.
A. P(t) = 
cos (ct)
B. P(t) = 
cos (ct + 8)
C. P(t) = 
cos (ct) - 
sin (ct)
D. P(t) = cos (ct)
