So berechnen Sie Inverse Trig Functions

learn.whatIsHeading

Inverse trigonometric functions (arcsin, arccos, arctan) find the angle given a ratio. arcsin(x) asks "what angle has sine = x?" They are essential for solving triangles when side lengths are known but angles are not.

Schritt-für-Schritt-Anleitung

1. 1arcsin(x): returns angle whose sine is x, range [−90°, 90°]
2. 2arccos(x): returns angle whose cosine is x, range [0°, 180°]
3. 3arctan(x): returns angle whose tangent is x, range (−90°, 90°)
4. 4arctan2(y,x): full-circle angle from coordinates (−180° to 180°)
