imam jednacinu ne znam sta joj je? pa ako mozete pomoci do sutra mi treba da predam javite uvjek mi izbacuje jedno te isto??? Code: /** Beispiel quadratische Gleichung */ import java.lang.Math; public class QGleichung { public static void main (String[] args) { double a = Double.parseDouble(args[0]); double b = Double.parseDouble(args[0]); double c = Double.parseDouble(args[0]); double d; // Diskriminante double re1, im1=0, re2, im2=0; // Real- und Imaginaerteil beider Loesungen System.out.println("zu loesen a*x*x + b*x + c = 0; a! = 0"); d = b*b - 4*a*c; if (d >= 0) { // 2 reelle Loesungen re1 = (-b/(2*a)) + ((Math.sqrt(d)) / (2*a)); re2 = (-b/(2*a)) + ((Math.sqrt(d)) / (2*a)); } else{ // 2 konjugiert komplexe Loesungen re1 = -b / (2*a); im1 = Math.sqrt(-d) / (2*a); re2 = re1; im2 = -im1; } System.out.println("x1 = " + re1 + " + i*" + im1); System.out.println("x2 = " + re2 + " + i*" + im2); }} |
