Trigonometric functions in Java with example

Java Math class provides various functions to support trigonometric calculations. Below table summarizes the methods.

 

Method	Description
acos(double a)	Return arc cosine of a value.
asin(double a)	Return arc sine of a value.
atan(double a)	Return arc tangent of a value.
cos(double a)	Returns the trigonometric cosine of an angle. Angle ‘a’ is specified in radians.
cosh(double x)	Returns the hyperbolic cosine of a double value.
sin(double a)	Returns the trigonometric sine of an angle. Angle ‘a’ is specified in radians.
sinh(double x)	Returns the hyperbolic sine of a double value.
tan(double a)	Returns the trigonometric tangent of an angle. Angle ‘a’ is specified in radians.
tanh(double x)	Returns the hyperbolic tangent of a double value.
