Question

Describe each of the following properties of the graph of the Sine Function, f(theta) = sin(theta) and relate the property to the unit circle definition of sine.

Amplitude
Period
Domain
Range
x-intercepts

Answer 1

Do you know much about the Unit Circle?

Answer 2

Not really. I have a picture of it though, i just don't know how it works.

Answer 3

sin is a repeating function or a continuous wave it's domain is all real numbers unless there is an imposed restriction.
the range of sign is always less than the absolute value of 1, or -1 to +1
look at your graph of the sin function from 0 to 2pi, y is 0 at x of 0, pi, and 2pi
amplitude unless modified by an A coefficient is 1
