: Determining a heading based on lateral displacement. ✅ Summary

The function, denoted as , is the inverse of the sine function. While sine takes an angle and gives a ratio, arcsine takes a ratio and returns the original angle. 1. Define the Domain and Range

Because a standard sine wave repeats forever, it isn't "one-to-one." To create a true inverse, mathematicians restrict the sine function's domain. : (The input must be between -1 and 1). Range : (The output is always in the first or fourth quadrant). 2. Understand the Unit Circle Connection On a unit circle, the sine of an angle represents the -coordinate. When you calculate arcsine
