Are the ratios 6: 18 and 2: 6 equivalent?

Treat them like fractions. Ratios are just fractions in a different form.



You can simplify 6/18. Find common factors. 2, 3, 6

Let's try and divide the top and bottom (numerator and denominator) by 3.
Then you get 2/6.
2/6 is equivalent to 2/6

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.
