Can you name some math terms starting with the letter "o" and give a short description of them?

Obtuse angle

Operation

Order of operation

"Order of operations" - the order in which you must simplify an equation 
"Origin" - center of the coordinate plane at (0,0)
"Outlier" - A number in a set of numbers that is way different than the rest (example: 1, 2, 3, 4, 5, 27. 27 is the outlier)
"octagon" - an 8 sided polygon 

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.
