1. Laboratoriya topshiriqlari

Quyidagi transsendent tenglamani oraliqni teng ikkiga bo’lish vaoddiy iteratsiya usuli yordamida yechimini aniqlovchi dastur tuzing:

3x+cosx+1=0 Oraliqni teng ikkiga bo’lish usuli: Dastur kodi:

#include #include using namespace std; double fi(double x)
{
return 3*x*x+x*cos(x)+x;
}
int main()
{
double a,b,c,e; cin>>a>>b; while(fi(a)*fi(b)>0)
{
cin>>a>>b;
}
cout<<"e ga qiymat bering: "; cin>>e;
while(fabs(b-a)>=c)
{
c=(a+b)/2; if(fi(a)*fi(c)<0)
b=c; else
a=c;
}
c=(a+b)/2; cout<}

Dasturdan natija olish:

Interatsiya usuli:

#include #include using namespace std; double fi(double x)

{
return 3*x*x+x*cos(x)+x;
}
int main()
{
double a,b,c,e; cin>>a>>b;
cout<<"e ga qiymat bering: "; cin>>e;
double x1, x2; x1=a;
x2=b;
while(fabs(a-x2)>=c)
{
x2=fi(x1); a=x1; x1=x2;

}
cout<<"x ning qiymati: "<
