As it happens sin() and cos() are also functions. A function has another property: all calls to a function with the same parameters, should return the same result. A method, on the other hand, is a function that is related to an object in an object-oriented language. It has one implicit parameter: the object being acted upon (and it's state).
Here you can see the functions name are same but parameter type and number of parameters are different. When two or more methods (functions) have the exact same method name, return type, number of parameters, and types of parameters as the method in the parent class is called method Overriding. Here you can see the method name, parameter and return type are same but one method is in the parent class and another one in the child class.
