已知圆心坐标，求圆上任意两点的角度 用java算出来
平面直角坐标系中，圆心坐标为（x0,y0）则圆上两点A(x1,y1)到B(x2,y2)的角度为：θ=arctan[(y2-y0)/(x2-x0)]-arctan[(y1-y0)/(x1-x0)]；--------------特殊情况：平面直角坐标系中，圆心坐标为坐标原点（0,0）则圆上两点A(x1,y1)到B(x2,y2)的角度为：θ=arctan(y2/x2)-arctan(y1/x1)；--------------在平面极坐标系中，若圆心为极点。则圆上两点A(r,θ1)到B(r,θ2)的角度为θ=θ2-θ1.
java问题
你的代码太乱了~~
给你改了改，差不多了，你把while(fab(t)=p); 里的fab()方法搞定估计就没问题了
public class arctan {
public static void main(String args[])
{
double z=0d,m=0d;
double y=16*arctan(1/5);
z=4*arctan(1/239);
m=y-z;
System.out.println(m);
}
static double arctan(double x)
{
double g=0,t=x,p=0.000001;
int n=0;
do
{
g=g+t;
n++;
t=-t*x*x/(2*n+1);
}while(fab(t)=p);
return g;
}
}
java中有反正弦，反余弦，反正切，反余切的方法吗
有这个工具包的，在java.math.Math类常中。
Math.PI 记录的圆周率
Math.sin 正弦函数
Math.asin 反正弦函数
Math.cos 余弦函数
Math.acos 反余弦函数
Math.tan 正切函数
Math.atan 反正切函数
Math.atan2 商的反正切函数
Math.toDegrees 弧度转化为角度
Math.toRadians 角度转化为弧度
java arctan
java arctan是什么，让我们一起了解一下？
arctan是java中数学运算的三角函数方法，tan() 三角正切，通过编程Java代码实现，常用的还有cos() 三角余弦，sin()为 三角正弦，asin() 正弦的反函数，cos() 余弦的反函数，tan() 正切的反函数。
他的源代码如下：
public class MainTest { public static void main(String[] args) { //求sin值 double sin = Math.sin(3.14); System.out.println("sin3.14=" + sin); //求cos值 double cos = Math.cos(0); System.out.println("cos0=" + cos); //求tan值 double tan = Math.tan(0.785); System.out.println("tan0.785=" + tan); //求arcsin double arcsin = Math.asin(1); System.out.println("arcsin1 = " + arcsin); //求arccos double arccos = Math.acos(1); System.out.println("arccos = " + arccos); //求arctan double arctan = Math.atan(30); System.out.println("arctan30 = " + arctan); //求弧度 double radians = Math.toRadians(180); System.out.println("180度角的弧度为" + radians); //求角度 double angle = Math.toDegrees(3.141592653589793); System.out.println("π的角度数为" + angle); //求以e为底的指数 double exp = Math.exp(1); System.out.println("以e为底指数为1的数为" + exp); //求以e为底e的平方的对数 double log = Math.log(Math.E * Math.E); System.out.println("以e为底e的平方的对数" + log); //求以10为底100的对数 double log10 = Math.log10(100); System.out.println("以10为底100的对数" + log10); //求100的平方根 double sqrt = Math.sqrt(100); System.out.println("100的平方根是" + sqrt); //求27的立方根 double cbrt = Math.cbrt(27); System.out.println("27的立方根是" + cbrt); //求10除以3的余数 double rest = Math.IEEEremainder(10, 3); System.out.println("10除以3的余数为" + rest); //求0.9向上取整 double ceil = Math.ceil(0.9); System.out.println("0.9向上取整" + ceil); //求2.49向下取整 double floor = Math.floor(2.49); System.out.println("2.49向下取整" + floor); //求最接近参数的整数值(若有两个满足条件的数据则取为偶数的数据) double rint = Math.rint(3.5); System.out.println("最接近参数的整数值" + rint); //获得(1,1)坐标与x轴夹角度数 double atan2 = Math.atan2(1, 1); System.out.println("坐标(1,1)的极坐标为" + atan2); //求3的5次方 double pow = Math.pow(3, 5); System.out.println("3的5次方" + pow); //4舍5入 double round = Math.round(3.5); System.out.println("3.5四舍五入为" + round); //计算2
请问谁能用java语言,为我写一个计算器的小程序
