If
B
is the standard basis of the space
P_(3)
of polynomials, then let
B={1,tt^(2),t^(3)}
. Use coordinate vectors to test the linear independence of the set of polynomials below. Explain your work.
1-7t^(2)-t^(3),t+6t^(3),1+t-7t^(2)
Write the coordinate vector for the polynomial
1-7t^(2)-t^(3)
.
(1,0,-7,-1)
Write the coordinate vector for the polynomial
t+6t^(3)
.
(0,1,0,6)
Write the coordinate vector for the polynomial
1+t-7t^(2)
.
(1,1,-7,0)
To test the linear independence of the set of polynomials, row reduce the matrix which is formed by making each coordinate vector a column of the matrix. If possible, write the matrix in reduced echelon form.
[[1,0,1],[0,1,1],[-7,0,-7],[-1,6,0]]∼
