Interactive Inverse Trigonometric Functions Visualization
Welcome to the Inverse Trigonometric Functions Explorer
This interactive visualization helps you understand inverse trigonometric functions (arcsin, arccos, arctan, etc.) and their properties. Inverse functions are created by restricting the domain of the original trigonometric functions to make them one-to-one.
What you can explore:
- arcsin(x) - Inverse of sine, domain [-1, 1], range [-π/2, π/2]
- arccos(x) - Inverse of cosine, domain [-1, 1], range [0, π]
- arctan(x) - Inverse of tangent, domain (-∞, ∞), range (-π/2, π/2)
- arccsc(x) - Inverse of cosecant, domain |x| ≥ 1
- arcsec(x) - Inverse of secant, domain |x| ≥ 1
- arccot(x) - Inverse of cotangent, domain (-∞, ∞), range (0, π)

Key Properties
Function: f(x) = arcsin(x)
Domain: [-1, 1]
Range: [-π/2, π/2]
One-to-One: Yes (restricted domain)
Key Concepts
Inverse Function: If f(x) = y, then f⁻¹(y) = x. The graph of f⁻¹ is the reflection of f across y = x.
Restricted Domain: Trigonometric functions are not one-to-one, so we restrict their domains to create inverses.
Range Restriction: The range of the inverse is the restricted domain of the original function.
