Inverse Trigonometric Functions Calculator

About this Calculator

This calculator will find the inverse trigonometric values for principal values in the ranges listed in the table. You can view the ranges in the inverse trigonometric function graphs.

Function Name	Abbreviation Functions	Range of Principal Values
Arcsine	Arcsin x or sin -1 x	-1 <= x <= 1 -π/2 <= y <= π/2
Arccosine	Arccos x or cos -1 x	-1 <= x <= 1 0 <= y <= π
Arctangent	Arctan x or tan -1 x	x, all real numbers -π/2 < y < π/2
Arccotangent	Arccot x or cot -1 x	x, all real numbers except 0 = π/2 -π/2 < y < π/2
Arcsecant	Arcsec x or sec -1 x	x <= -1 and x >= 1 0 <= y < π/2 or π/2 < y <= π
Arccosecant	Arccsc x or csc -1 x	x <= -1 and x >= 1 -π/2 <= y < 0 or 0 < y <= π/2
