Chapter 4.2, Problem 4.2.7CP

Program Plan Intro

Mathematical functions:

• The “Math” class in the Java provides many useful methods for performing common mathematical functions.
• The “Math” class can be categorized as an exponent methods, trigonometric methods and service methods.
• The “Math” class also provides two “double” constants, “PI” and “E”.

Trigonometric method:

Trigonometric method consists of eight methods. They are:

• sin (randians) – it will return the sine of an angle in radians
• asin (a) – it will return the angle in radians for the inverse of sine

Exponent method:

Exponent methods consist of five methods. They are:

exp (x) – it will return “e” raised to power of “x”.

log (x) – it will return the natural logarithm of “x”
