SOAL UAS GENAP METODE NUMERIK 2011/2012

Syarat: 
#jawaban di nyatakan dalam bentuk pecahan atau desimal (dengan menerapkan aturan pembulatan 4 angka di belakang koma, berdasarkan metode pembulatan gauss).

Ex: 3,27569 =>  3,2757  atau  3,27235 => 3,2724;


BAG 1
 1.   
1.      Diketahui:
e2  = 7.3891;   e3= 20.0855;  e4= 54.5982

Tentukan nilai e(2.89)  ­­­­­­dengan menggunakan metode:
a)      Interpolasi Kuadratik
b)      Interpolasi Polino Lagrange
c)      Hitunglah galat (nilai selisih error) yang terjadi berdasarkan hasil perhitungan tiap metode di atas (jawaban 1.a dan 1.b), bila dibandingkan dengan nilai sejati-nya!

2.      Selesaikan sistem persamaan linear berikut, dengan menggunakan metode matriks invers:
a.       5x+95y = 150
15x+275y = 350

b.      5x+4y+8z = 25
3x+6y+9z = 75
2x+y+15z = 125


BAG 2


1.      Selesaikan sistem persamaan linier berikut dengan metode iterative Gauss-Seidel. Lakukan iterasi hingga | Ɛ0 | <= 0.05%
11a           5b        3c        d          = 88
-a              13b      -7c       3d        = 78
3a             -7b       17c      -5d       = 68
-7a            3b        -5c       19d      = 38

2.      Diketahui data dalam tabel berikut merupakan nilai dari fungsi  f(x)= log5  x

Perkiraan nilai log5 (18.81) dengan menggunakan metode berikut, dan bandingkan dengan nilai sejatinya!
a)      Interpolasi Polinom Lagrange Orde1
b)      Interpolasi Orde2
c)      Interpolasi Polinom Lagrange Orde3
d)     Interpolasi Kubik
