What value for n makes this equation true? 4 • 63 = (4 • 60) + (4 • n)

4* 63 = (4* 60) + (4*n)
252 = 240 + 4n
252 - 240 = 240 - 240 + 4n
12 = 4n
4n : 4 = 12: 4
n = 3

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.
