How many such polynomials are there. Sketch one of them. 5. Consider the linear system A~x = ~ b , where A = 1 a 1 2 b 12 c . For which choices of a,b,c does the system always have a unique solution. For the other choices of a,b,c give examples to show that the system may have either innitely many or no solutions. 6. Suppose that ~v 1 ,...,~v n are n vectors in R n . Prove the following theorem: If ~v i ~v j = 0 for 1 i < j n , then { ~v 1 ,...,~v n } is linearly indepedent. 1...
