📐 Inverse Trig Functions Calculator
📐 INVERSE TRIG FUNCTIONS — OVERVIEW
Inverse trigonometric functions return the angle whose trig value is the given input. They are essential in geometry, physics, engineering, and navigation. The six functions are: arcsin (sin⁻¹), arccos (cos⁻¹), arctan (tan⁻¹), arccsc (csc⁻¹), arcsec (sec⁻¹), and arccot (cot⁻¹).
📋 DOMAINS AND RANGES
arcsin(x): Domain [−1, 1] → Range [−90°, 90°]
arccos(x): Domain [−1, 1] → Range [0°, 180°]
arctan(x): Domain (−∞, +∞) → Range (−90°, 90°)
arccsc(x): Domain |x| ≥ 1 → Range [−90°, 0°) ∪ (0°, 90°]
arcsec(x): Domain |x| ≥ 1 → Range [0°, 90°) ∪ (90°, 180°]
arccot(x): Domain (−∞, +∞) → Range (0°, 180°)
📊 KEY IDENTITIES
Complementary: arcsin(x) + arccos(x) = π/2 (90°)
Reciprocal: arccsc(x) = arcsin(1/x), arcsec(x) = arccos(1/x)
arccot: arccot(x) = π/2 − arctan(x) = arctan(1/x) for x > 0
Odd: arcsin(−x) = −arcsin(x), arctan(−x) = −arctan(x)
Even: arccos(−x) = π − arccos(x)
⚠️ COMMON MISTAKES
Domain errors: arcsin and arccos are only defined for x ∈ [−1, 1]. arccsc and arcsec need |x| ≥ 1.
Inverse ≠ reciprocal: sin⁻¹(x) is the inverse function, NOT 1/sin(x).
Range confusion: Each function has a specific principal value range. Results outside this range require adding/subtracting multiples of the period.
Degree/Radian mix: Always check which output unit is selected before using the result.

What Are Inverse Trigonometric Functions?
Definition of Inverse Trigonometric Functions
Inverse trigonometric functions are mathematical functions that reverse the action of basic trigonometric functions. While trigonometric functions take an angle as input and return a ratio, inverse trigonometric functions do the opposite.
For example:
Sine → Ratio
Inverse sine (arcsin) → Angle
Using an inverse trigonometric functions definition, we can say:
If sin θ = x, then θ = sin⁻¹(x) or arcsin(x)
An inverse trigonometry calculator automates this process accurately.
