a. draw a diagram to represent the situation.
yte
b. write and simplify an expression representing the square's perimeter.
c. write and simplify an expression representing the square's area.
d. write and simplify an expression representing the diagonal of the square.

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.
