所以我正在研究这个项目。一切都很好,但数学不对。如果你输入全部2,s你应该得到结果(0,0),但我得到(1,-1)。如果我能得到一双新鲜的眼睛,让我知道我的计算错误在哪里,我做了什么,我真的很感激!
System.out.println("Please enter the value for d: ");
int d = IO.readInt();
System.out.println("Please enter the value for f: ");
int f = IO.readInt();
System.out.println("Please enter the value for g: ");
int g = IO.readInt();
System.out.println("Please enter the value for m: ");
int m = IO.readInt();
System.out.println("Please enter the value for b: ");
int b = IO.readInt();
double y = (f - m);
double u = (4*d*(g-b));
double i = (2*d);
double o = ((f+m)*(f+m));
/*
* x=(-(f-m)(+ or -)(sqrt((f-m)^2) - (4d(g-b))
* 2d
*
* x=-b(+ or -)(sqrt((b^(2))-4ac))
* 2a
*/
double x = ((0-(y))+(Math.sqrt(o)-((u)))/(i));
double x1 = ((0-(y))-(Math.sqrt(o)-((u)))/(i));
IO.outputStringAnswer(x + " , " + x1);
答案 0 :(得分:0)
检查o
值,它与您的评论不符......
