Presentation Transcript

  1. Interpolacija Tabelarni podaci U čvoru greška interpolacije je jednaka nuli Greška interpolacije Tražimo vrednost y za x=5 y f(x) Pn(x) x

  2. Inverzna interpolacija Tabelarni podaci Tražimo vrednost x za y=3 y f(x) Pn(x) x x x Više rešenja (funkcija mora biti monotona)

  3. Diferenciranje Velikarazlika (čak i u predznaku) Tabelarni podaci f’(x) Pn’(x) Tražimo prvi izvod za x=3 y f(x) Pn(x) x

  4. Integracija Tabelarni podaci Greškemogu da se potiru Tražimo vrednost integrala od x=2 do x=4 - + f(x) x2 x1 h
