Sine is a function used in trigonometry, defined as the y coordinate of a point which is x radians on the unit circle
Info
Sine appears in calculus a fair amount as well as other subjects (that should link to "geometry").
Integral and derivative
$ \int{sin{(x)}} dx=-cos{(x)} $ is the integral and $ \frac{d}{dx}(sin(x))=cos(x). $ is the derivative
Range of sine
The range of sine is $ -1 \le sin(x) \le 1 $.
