I feel extremely unprepared for my maths exam, Particularly paper 2. I didn't have the greatest of teachers for the past two years and I am wondering how best to learn topics for maths paper 2, Particularly construction? Thanks. Also, how does one distinguish a sine from a cosine graph?

A sine graph goes through the origin

Assuming that no constant is added to it, then it goes through the y axis at the y value of the centreline
