Evaluate, 45 + 22 divided by 11 x [(60 - 15)x 60]+25}=

45+22=67
67/11=6
60-15=45
45+25=70
70x6= 420

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.
