Java Math trigonometric methods

Introduction

Math class contains the following methods for performing trigonometric functions:

Method Description
sin(radians) Returns the trigonometric sine of an angle in radians.
cos(radians) Returns the trigonometric cosine of an angle in radians.
tan(radians)Returns the trigonometric tangent of an angle in radians.
toRadians(degree) Returns the angle in radians for the angle in degree.
toDegree(radians) Returns the angle in degrees for the angle in radians.
asin(a)Returns the angle in radians for the inverse of sine.
acos(a)Returns the angle in radians for the inverse of cosine.
atan(a)Returns the angle in radians for the inverse of tangent. 
Math.toDegrees(Math.PI / 2)     //90.0 
Math.toRadians(30)              //0.5236 (same as pi/6) 
Math.sin(0)                     //0.0 
Math.sin(Math.toRadians(270))   //-1.0 
Math.sin(Math.PI / 6)           //0.5 
Math.sin(Math.PI / 2)           //1.0 
Math.cos(0)                     //1.0 
Math.cos(Math.PI / 6)           //0.866 
Math.cos(Math.PI / 2)           //0 
Math.asin(0.5)                  //0.523598333 (same as PI/6) 
Math.acos(0.5)                  //1.0472 (same as PI/3) 
Math.atan(1.0)                  //0.785398 (same as PI/4)
