him and 25 km away. He also sees a ship 42 km away
and on a bearing of 080°. Calculate:
a) the distance of the boat from the ship
b) the bearing of the boat from the ship.

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.
