Root Explanation

Arcsine is formed from "arcus" (from Latin, meaning bow or arc) and "sinus" (from Latin, meaning curve or fold). The term refers to the angle whose sine is a given number, thus relating to the arc of a circle.

Memory Tip

Think of 'arc' as a bow shape and 'sine' as a curve — arcsine helps you find the angle related to that curve.
