Example
ASIN(1) returns 90 (Degrees mode).
ACOS Arc cosine: cos
–1
x. Output range is from 0° to 180°, 0 to
π, or 0 to 200 grads. Inputs and outputs depend on the
current angle format. Also accepts complex numbers.
Output will be complex for values outside the normal
COS domain of .

Example
ACOS(1) returns 0 (Degrees mode).
ATAN Arc tangent: tan
–1
x. Output range is from –90° to 90°,
2π/2 to π/2, or –100 to 100 grads. Inputs and outputs
depend on the current angle format. Also accepts
complex numbers.
