Java提供了三角函数方法,直接调用cos()方法就可以根据x坐标计算出y坐标。需要注意的是,cos()方法输入的参数是弧度值,要进行坐标转换,同样,得到的结果也要进行转换处理。-
Java provides a trigonometric method, a direct call cos () method can be calculated based on the x coordinate y coordinates. It should be noted that the parameter cos () method is entered in radians, to coordinate conversion, the same, the result should be conversion.
