Sine is the ordinate of the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.
In a right triangle, the ratio of the length of the side opposite an acute angle to the length of the hypotenuse. Yeah yeah, I know...what's hypotenuse mean? It's The side of a right triangle opposite the right angle.
There...now, did that answer your question? IS it all becoming clear again for you now?
Mind if I ask why you are asking of Sine? Is it because you have heard people say "sining the kite"? If so, I'm sure by now we have you clear and straight.
