Understanding Arcsine (sin⁻¹)
Arcsine, denoted as sin⁻¹(x) or asin(x), is the inverse function of sine. It answers the question: "What angle has a sine of x?". In simpler terms, if sin(θ) = x, then arcsin(x) = θ.
The arcsine function is typically defined for input values between -1 and 1, inclusive, and its output is an angle in radians or degrees. The principal value of arcsine is usually given in the range of -π/2 to π/2 radians (-90° to 90° degrees).
This calculator helps you find the arcsine of a given value and visualizes the angle on a unit circle, enhancing your understanding of trigonometric concepts. It's useful in various fields like physics, engineering, and computer graphics where angles need to be determined from sine values.
