1. Plural of arcsine; the inverse trigonometric function that returns the angle whose sine is a given number, or the set of such angles.
Usage: mathematics; trigonometry

Examples

• The arcsines of values between -1 and 1 are defined in trigonometry.
• To find the angle, we calculate the arcsines of the ratio of opposite to hypotenuse.
• In calculus, the derivative of arcsines appears frequently in integration problems.
• The arcsines function is often denoted as sin⁻¹ or arcsin in mathematical notation.
• Students learn to evaluate arcsines using both calculators and reference tables.
