«Dasturiy injiniringi» mutaxassisligi 1-kurs 104-19 guruh talabasi Aytmuratov Ruslanbekning

Masalaning qo’yilishi:

3–misol: x ning qiymatida f = 2x² + 3x – 9 funktsiyasinig qiymatini hisoblang ;
41–misol: Boshlang’ich tezligi ₀ m/s bolgan avtomobil m/s² tezlanish bilan
harakatlanib boshladi. Avtomobil t sek vaqitta qancha jo’l (m) bosishini
aniqlang ;

   Masalaning yechilishi:
   

3–misol.
x ning qiymatida f = 2x² + 3x – 9 funnktsiyasinig qiymatini aniqlovchi dasturni
Java tilida tuzamiz :

1. 
   Dastu’r kodi:
   

package misol3;

import java.util.Scanner;
public class Misol3 {

public static void main(String[] args) {

Scanner in=new Scanner(System.in);
double x,f;
System.out.print("x=");
x = in.nextDouble();
f = 2*Math.pow(x,2) + 3*x - 9;
System.out.println("f="+f);
}
}

2. 
   Na’tiyja :
   

x=5
f=56.0
