sines
Opposite over hypotenuse
Sines is the plural of sine, a trigonometric function fundamental to mathematics and physics.
The sine of an angle in a right triangle is the ratio of the opposite side to the hypotenuse.
Sines appear constantly in calculations involving waves, oscillations, and circular motion: The engineer computed the sines of various angles to model the sound wave.
