Write the equation of a sine function with Amplitude = 2 and Period = 2. Type the equation in the form y = Asin(@x) or y = Acos(@x). Select the correct choice below and fill in the answer box to complete your choice. O A. There are two equations; the equation when w< 0 is y = and the equation when w >0 is y = (Simplify your answers. Type an exact answer, using t as needed. Use integers or fractions for any numbers in the expression.) O B. There are two equations; the equation when A<0 is y = and the equation when A>0 is y = (Simplify your answers. Type an exact answer, using t as needed. Use integers or fractions for any numbers in the expression.) O C. There is one equation. It is y = (Simplify your answers. Type an exact answer, using t as needed. Use integers or fractions for any numbers in the expression.)
