Sin-1 Explained

Sin-1, SIN-1, sin-1, or sin^-1 may refer to:

• SIN-1, Linsidomine (3-morpholinosydnonimine), a drug acting as a vasodilator
• sin x-1 = sin(x)-1 = -(1-sin(x)) = -cvs(x) or negative coversine of x, the additive inverse (or negation) of an old trigonometric function
• sin^-1y = sin^-1(y), sometimes interpreted as arcsin(y) or arcsine of y, the compositional inverse of the trigonometric function sine (see below for ambiguity)
• sin^-1x = sin^-1(x), sometimes interpreted as (sin(x))^-1 = = csc(x) or cosecant of x, the multiplicative inverse (or reciprocal) of the trigonometric function sine (see above for ambiguity)
• sin x^-1, sometimes interpreted as sin(x^-1) = sin, the sine of the multiplicative inverse (or reciprocal) of x (see below for ambiguity)
• sin x^-1, sometimes interpreted as (sin(x))^-1 = = csc(x) or cosecant of x, the multiplicative inverse (or reciprocal) of the trigonometric function sine (see above for ambiguity)
