Short for the word sine. It is a stupid and idiotic trigonometric function. Gives headaches to calculus students everywhere. Teachers try to give there students a stupid story about an indian, but they never really care, and when taught at seven in the morning, it could never really be understood.
It should be a sin to teach us about sin this early in the morning and expect us to remember it.
