在java三角函数怎么用

Math.sin

都在下面啦，自己挑挑看 public void test(){ System.out.println("ExampleUnitTest-Sin 90°="+Math.sin(Math.PI/2)); System.out.println("ExampleUnitTest-30°-1="+Math.toDegrees(Math.PI/6)); System.out.println("ExampleUnitTest-30°-2="+Math.toDegrees(Math.asin(Math.sin(Math.PI/6)))); System.out.println("ExampleUnitTest-sin30°="+Math.sin(Math.PI/6)); System.out.println("ExampleUnitTest-asin 0.5="+Math.toDegrees(Math.asin(0.5)));//求一个正弦值的弧度对应角度 System.out.println("ExampleUnitTest-cos 60°=="+Math.cos(Math.PI/3)); System.out.println("ExampleUnitTest-tan 45°=="+Math.tan(Math.PI/4)); System.out.println("ExampleUnitTest-atan=="+Math.atan(Math.tan(Math.PI/4)));//求孤独 System.out.println("ExampleUnitTest-atan1=="+Math.atan(1));//求斜率对应的孤独 System.out.println("ExampleUnitTest-atan1=="+Math.toDegrees(Math.atan(1)));//求斜率对应的孤独的对应角度 }
