- Math class
  - java.lang package
  - Provides mathematical functions
  - Class methods
    - Absolute value
    - Trigonometric
    - Floor, ceiling, round
    - Min/max
    - Logarithms and exponentials
    - Degrees/radians
  - Class constants
    - PI = 3.1415969...
    - E = 2.71828182...

Quick Check:
1. a. (1/2) evaluates to 0 because of integer division, so you'll lose the value of the square root
   b. sqrt is a class method, so you must refer to it with the class name: "Math.sqrt"
   c. exp only takes one argument; here, it's being mistaken for the pow method
   d. Math is a class name, and must be capitalized; remember, Java is case sensitive
2. a., b. The programmer probably doesn't realize that the trigonometric functions of Math operate on radians, not degrees
