1. The inverse trigonometric function that returns the angle whose sine is a given number; denoted as arcsin or sin⁻¹.
Usage: mathematics; Also called inverse sine

Examples

• The arcsine of 0.5 is approximately 30 degrees or π/6 radians.
• To find the angle, we need to apply the arcsine function to both sides of the equation.
• The domain of arcsine is restricted to values between -1 and 1.
• Students learn about arcsine in trigonometry when studying inverse functions.
• The calculator's arcsin button computes the arcsine of the input value.
