1. Write an equation of the following using the particular function.

1. The function is sine. The amp is 2 and the domain is [0, 2].

I got y=2sin(pie(x))

but i plugged that in my calc and it doesnt look like the graph on my worksheet

2. The function is cosine. The amp is 3 and the domain is [-pie/3, 11pie/3]

I got y=3cos(3/5x-pie)

thanks!!
