If the top of a 4.50 m ladder reaches twice as far up a vertical wall as the foot of the
ladder is out from the base of the wall, how far up the wall does the ladder reach?
Draw a diagram. Give your answer to two decimal places

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.
