The Ruby Math module provides the Ruby programmer with an extensive range of methods for performing mathematical tasks.
There is a list of methods with their description
| Method name | Description |
|---|---|
| Math.acos, Math.acos! | Arc cosine |
| Math.acosh, Math.acosh! | Hyperbolic arc cosine |
| Math.asin, Math.asin! | Arc sine |
| Math.asinh, Math.asinh | Hyperbolic arc sine |
| Math.atan, Math.atan!, Math.atan2, Math.atan2! | Arc tangent. atan takes an x argument. atan2 takes x and y arguments |
