Ako vypočítať Inverse Trig Functions

Čo je Inverse Trig Functions?

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.

Sprievodca krok za krokom

  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°)

Worked Examples

Vstup

Vstup
arctan(1)
Výsledok
45°
tan(45°) = 1
Vstup
arccos(0)
Výsledok
90°
cos(90°) = 0
