Find the angular size of a circular object with a 1-inch diameter viewed from a distance of 4 yards. The angular size of the object is Iº.
(Do not round until the final answer. Then round to the nearest hundredth as needed.)

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
