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).
Both Java and Go have the functions concept though they are slightly different when compared altogether. In Java, if someone is referring to a function, they are actually referring to the specific body of the code, which include the name, the return type and the parameters rather than just the function itself.
