Math is a pre-defined class in the package java.lang. It contain various predefined functions in it that help the users to carry out various mathematical operations in their programs.
Various Math Functions are::
Math.pow(x,y) => x^y
Math.sqrt(x) => Square root of 'x'
Math.tan(x),sin(x),cos(x) => tan, sin, cos of 'x' respectively
there are also other functions like Math.ceil,Math.floor,Math.mod,etc.
In Java, there are no functions. They call it method and you can define it within a class.
A function created by the user. In Java, functions are attached to a class, and are called "methods".
Math is the class, and sqrt() is the method.
At the top of your program: import math or from math import * The second one imports all math functions, like fact() for factorial.
Pure functions are those which do not modify the state of an object. Most often these are functions which take arguments and return a result.
Every method in java that isn't a class (static) method is automatically "virtual." If you want to disable virtual overrides, make the method "final" in the base class.
the Math class contains a number of mathematical functions that we may commonly need to use in our programs. Instead of coding it ourselves, the founders of java have created a class that would help us with the same. For example: Math.round() is used to round off a decimal value to its nearest whole number Math.cos() will return the mathematical cosine of the value Math.log() will return the logarithmic value of the number etc...
The java. lang. math class allows for the use of many common mathematical functions that can be used while creating programs
Who create Java & when? Why he create java ? What are mane functions of it?
In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

Same as in other languages. To organize commands into logical pieces. However, in Java the functions are called "methods". This is related to the fact that in Java, methods or functions are defined as part of a class.
for loop function
Classes are well organised functions in java which help discriminate between two different functions.
Math is the class, and sqrt() is the method.
At the top of your program: import math or from math import * The second one imports all math functions, like fact() for factorial.
He memorized tables of functions, exponential functions, logarithmic functions, etc, ... try looking up "handbook of mathematical functions"
Pure functions are those which do not modify the state of an object. Most often these are functions which take arguments and return a result.
its a .dll file that provides API functions to your user profile.. like JAVA API functions..
