Csc-1

From Wikipedia, the free encyclopedia

Csc-1, CSC-1, csc-1, or csc−1 may refer to:

  • csc x−1 = csc(x)−1 = excsc(x) or excosecant of x, an old trigonometric function
  • csc−1y = csc−1(y), sometimes interpreted as arccsc(y) or arccosecant of y, the compositional inverse of the trigonometric function cosecant (see below for ambiguity)
  • csc−1x = csc−1(x), sometimes interpreted as (csc(x))−1 = 1/csc(x) = sin(x) or sine of x, the multiplicative inverse (or reciprocal) of the trigonometric function cosecant (see above for ambiguity)
  • csc x−1, sometimes interpreted as csc(x−1) = csc(1/x), the cosecant of the multiplicative inverse (or reciprocal) of x (see below for ambiguity)
  • csc x−1, sometimes interpreted as (csc(x))−1 = 1/csc(x) = sin(x) or sine of x, the multiplicative inverse (or reciprocal) of the trigonometric function cosecant (see above for ambiguity)[citation needed]
