Introduction to Programming in Java: An Interdisciplinary Approach, second edition

APIs

`public class Math`
`double`	`abs(double a)`	absolute value of `a`
`double`	`max(double a, double b)`	maximum of `a` and `b`
`double`	`min(double a, double b)`	minimum of `a` and `b`
Note 1: `abs()`, `max()`, and `min()` are defined also for `int`, `long`, and `float`.
`double`	`sin(double theta)`	sine of `theta`
`double`	`cos(double theta)`	cosine of `theta`
`double`	`tan(double theta)`	tangent of `theta`
Note 2: Angles are expressed in radians. Use `toDegrees()` and `toRadians()` to convert. Note 3: Use `asin()`, `acos()`, and `atan()` for inverse functions.
`double`	`exp(double a)`	exponential (e^a)
`double`	`log(double a)`	natural log (log_e `a`, or ln `a`)
`double`	`pow(double a, double b)`	raise `a` to the `b`th power (`a`^b)
`long`	`round(double a)`	round `a` to the nearest integer
`double`	`random() ...`
