Unformatted text preview: 1. Linear Algebra Problems 1. (too easy) Find the linear combination 3 a 1 + 5 a 2- a 3 of the vectors a 1 = < 4 , 3 , 1 ,- 2 >, a 2 = < 1 , 2 ,- 3 , 2 >, a 3 = < 16 , 9 , 1 ,- 3 > . 2. (too easy) Find the vector bfx from the equation a 1 + a 2 + 3 a 3 + 4 x = 0 where a 1 = < 5 ,- 8 ,- 1 , 2 >, a 2 = < 2 ,- 1 , 4 ,- 3 >, a 3 = <- 3 , 2 ,- 5 , 4 > . 3. (easy) Are the vectors below linearly independent? a 1 = < 4 ,- 2 , 6 >, a 2 = < 6 ,- 3 , 9 > ; 4. (easy) Find a basis of the system of vectors below, and express the rest of the vectors in that basis. a 1 = < 2 , 1 >, a 2 = < 3 , 2 >, a 3 = < 1 , 1 >, a 4 = < 2 , 3 > ; 5. When does a system of vectors have a unique basis? 6. Find the general solution, and a particular solution of the system below using the Gauss elimination metod. 5 x 1 + 3 x 2 + 5 x 3 + 12 x 4 = 10 2 x 1 + 2 x 2 + 3 x 3 + 5 x 4 = 4 x 1 + 7 x 2 + 9 x 3 + 4 x 4 = 2 . 7. (pre-calc-ish, but...) Find a degree two polynomial with real coefficients, f ( x ) , such that f (1) = 8...
