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

For the answer to the question above, 
  I will use t instead of theta. The question asks about f(t) = sin(t), not about some more general sine function, so I would answer as follows: 

* Amplitude: 1, because largest y-coordinate of unit circle is 1 
* Period: 2pi because the circumference of a unit circle is 2pi and t is measured as arc-length around the circle. 
* Domain: All real numbers, because t can go as many times around the circle, both clockwise (positive) and counterclockwise (negative) as you like. 
* Range: [-1, 1] because the y-coordinate on the unit circle ranges between -1 and 1 inclusive 
* x-intercepts: values of t, where y=0, namely 0 plus any integer multiple of 2pi, and pi + any integer multiple of 2pi, or, more succinctly, k pi where k is any integer.

Hello there.

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.

x-intercepts

The correct answer is -20y

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
