Integral chegaralari [a,b] oraliqni bo‘luvchi qadami
h=(b-a)/n=(3.5-2)/10=0.15
bo‘lganda, bo‘linish nuqtalari xi=a+ih, i=1,…,10 o‘lsa, nuqtalarni [2,3.5] oraliqda aniqlab, bu nuqtalarda integral ostidagi funksiya qiymatlarini topamiz.
x0=2.00
x1=2.15
x2=2.30 y2=f(8.30)=0.3350
x3=2.45 y 3=f(7.15)=0.3371
x4=2.60 y4=f(8.60)=0.3402
x5=2.75 y 5=f(8.75)=0.3443
x6=2.90 y 6=f(8.90)=0.3494
x7=3.05 y 7=f(3.05)=0.3558
x8=3.20 y 8=f(3.20)=0.3637
x9=3.35 y 9=f(3.35)=0.3733
x10=3.50 y 10=f(3.50)=0.3849
Yuqoridagi x va y qiymatlariga ko‘ra
1) o‘ng to‘g’ri to‘rtburchaklar formulasiga asosan:
=0.15(0.3338+0.3350+0.3371+0.3402+0.3443+0.3494+ +0.3558+0.3637+0.3733+0.3849)=0.5276;
2) Trapetsiyalar formulasiga asosan:
=0.15( +0.3338+0.3350+0.3371+0.3402+ +0.3443+0.3494+0.3558+0.3637+0.3733)=0.15*3.4917=0.523;
3)Simpson formulasiga asosan:
[0.3333+0.3849+4(0.3338+0.3371+0.3443+0.3558+ +0.3733)+2(0.3350+0.3402+0.3494+0.3637)]=0.05(0.7182+4*1.7493+ +2*1.3883)=0.05*10.4720=0.5236.
