The Inverse Sine Function. . Consider the function f(x) = sin (x) on its natural domain. We know that it fails the HLT, so it is not 1-1, therefore it is not invertible.. However, if we restrict the domain we can define the inverse of sine.. Def: The inverse sine function, denoted by arcsin or sin

The sine function and its inverse
sin(sin-1 x) = x for every x in [-1,1]
sin-1(sin x) = x for every x in [-?/2, ?/2]
2) The cosine function and its inverse
cos(cos-1 x) = x for every x in [-1,1]
cos-1(cos x) = x for every x in [0, ?]
3) The tangent function and its inverse
tan(tan-1 x) = x for every real number x
tan-1(tan x) = x for every x in (-?/2, ?/2)
