Java – Find Sine of Angle – sin() Method – Examples & Explanation

sin() method is used to find out a trigonometric ratio sine of an angle in JAVA, measured in radians. sin() method exists in “Math” library of JAVA programming language.

Syntax of sin() Method in JAVA

The syntax of sin() method in JAVA Language is:

 

Arguments of sin() method in JAVA

x – Where x is any valid java double value (represents an angle), measured in radian.

 

Error Handling

If the x parameter is not a number sin() method returns an error.
If argument is empty or no argument is used, sin() method returns an error

 

Return Value of sin() method in JAVA

sin() method returns numeric value (double) after calculating sine of given argument (angle), in radian.
if argumment (X) is NaN, sin() method returns NaN.
if argumment (X) is infinity, sin() method returns NaN.
if argumment (X) is zero, sin() method returns Zero (Positive or negative with the same sign as argument).
Note: The return value must be within 1 ulp (unit of the last place unit of least precision) of the exact return value and return value must be semi-monotonic.

 

sin() Method example in JAVA when argument is a numeric value


Output:
0.8509035245341184

 

sin() Method Example in Java when argument = zero


Output:
0.0

 

Sin() Method Example in when argument is a string


Output:
The above code example returns an error because of incompatible data type. The string type cannot be converted into double.
