TUGAS 2
1. a. Tentukan a.b jika diketahui a = [4,8,-9] dan b = [-8,12,-4]
b. Tentukan sudut antara a = [-1,4,8,-4] dan b = [2,0,4,0]
c. Tentukan k agar a = [ 2,k,-3] tegak lurus dengan b = [0,-k,4]
2. Misal u = [4,-4,4] v = [0,1,0]
w = [-1,-2,1]
Tentukan :
a. w. ( v x w )
b. ( u x v ) . (v x w )
3. Tulis p sebagai kombinasi linear dari { a, b, c }
a. P = [8,10,12]
a = [1,2,3] b = [3,2,1] c = [3,4,5]
b. P = [ 22,24,26] a = [ 1,2,3] b = [3,2,1] c = [3,4,5]
