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 |
