Whats the graph called that goes back to the beginning?

SOUNDS like a cycle to me. Hence words like "recycle" =/. What else could it be?

For water, it's called a cycle--the water cycle. A graph that goes back to the beginning is usually called periodic, but cyclic could also be used.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
