Preguntas Frecuentes
What is arccos?
Arccos (inverse cosine) returns the angle whose cosine equals the given value. It is the inverse function of cosine.
Why does arccos range from 0° to 180°?
This range ensures arccos is a proper function (one output per input). Cosine takes each value in [-1,1] exactly once in the interval [0°, 180°].
How are arcsin and arccos related?
arcsin(x) + arccos(x) = 90° for any x in [-1, 1]. They are complementary angles.
