What is the third step in simplifying this equation (10-7) + (2*14/4)

The first step is 10 - 7 + (2)(14)/4 which equals (2-step) = 3 + 28/4 (3-step) = 3 + 7 (finale-step) = 10

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.
