Question

Write the equation of a sine function with Amplitude-7 and Period: 2 . Type the equation in the form y= Asin(x) or y= Acos(mx) Select the correct choice below and fill in the answer box to complete your choice 0 A. There is one equation. It is y= O B. There are two equations, the equation when A 0 is y and the equation when A 0 is y ° C. There are two equations, the equation when ? 0 is y (Simplify your answers. Type an exact answer, using ? as needed. Use integers or fractions for any numbers in the expression.) (Simplify your answers. Type an exact answer, using ? as needed. Use integers or fractions for any numbers in the expression.) (Simplify your answers. Type an exact answer, using ? as needed. Use integers or fractions for any numbers in the expression.)

Explanation / Answer

Amplitude and period are always positive. So the correct option is A

Here. A=7, Period , 2pi/omega =2pi

So we get omega=1

Hence the required equation is y= 7cos(x)
