This calculator calculates arcsine, arccosine, arctangent, arccotangent, arcsecant and arccosecant and will determine the angle value in both degree and radian measure.
What is Arcsecant
The arcsecant (arcsec (x)) of the number x, is the angle α given in radian measure, such that sec α = x.
Calculate arcsecant means to find an angle α whose secant is equal to the number x.
Range (in radians and degrees):
0 ≤ α < π/2 or π/2< α ≤ π
0° ≤ α < 90° or 90° < α ≤ 180°
1 ≤ x ≤ −1
