I need all details. Thx 9. Consider a basis B = {bi, b2} of a sulspoo, W of R4 where -3 (a) Determine the coordinates of x(3,-1,-2,1) in the basis B (i.e. fnd x). (b) Suppose that bl el-C2 and b2 2c1 +c2. Determine the coordinates of x = (3.-1,-21) in the basis C = {c,,c) (i.e. find [x le) (e) Suppose t dbb an d2b 3b s D- di da a basis of W Why or why not? 9....
can anybody explain how to do #9 by using the theorem 2.7? i know the vectors in those matrices are linearly independent, span, and are bases, but i do not know how to show them with the theorem 2.7 a matrix ever, the the col- ons of B. e rela- In Exercises 6-9, use Theorem 2.7 to determine which of the following sets of vectors are linearly independent, which span, and which are bases. 6. In R2t], bi = 1+t...
