Explanation Formula used: Period and Amplitude A sin B x and A cos B x : The graphs of f ( x ) = A sin B x and f ( x ) = A cos B x where A ≠ 0 and B ≠ 0 have period 2 π | B | and amplitude | A | . Calculation: It is given that the population of foxes in a certain region over a 2-year period is estimated to be P 1 ( t ) = 400 + 50 sin ( π t 12 ) where t represents the month and the population of rabbits in the same region at time t is given by P 2 ( t ) = 3000 + 500 cos ( π t 12 ) . From the equation P 1 ( t ) = 400 + 50 sin ( π t 12 ) , it is noticed that 50 sin ( π t 12 ) is in the form of A sin B x has period 2 π π 12 = 24 and its amplitude | A | = 50 . Now from the equation P 2 ( t ) = 3000 + 500 cos ( π t 12 ) , it is noticed that 500 cos ( π t 12 ) is in the form of A cos B x has period 2 π π 12 = 24 and its amplitude | A | = 500
