Exercises 1.3.3
UV
1(a) Yes, as the three vectors are linearly independent and span three-
dimensional space.
IA
1(b) No, since they are linearly dependent

⎣ 2 ⎦ − 2⎣ 0⎦ = ⎣ 2 ⎦
5 1 3
AP
1(c) No, do not span three-dimensional space. Note, they are also linearly
dependent.

Rotates the (e1, e2) plane through π/4 radians about the e3 axis.
3 By checking axioms (a)–(h) on p. 10 it is readily shown that all cubics
ED
ax3 + bx2 + cx + d form a vector space. Note that the space is four dimensional.
3(a) All cubics can be written in the form
??
ax3 + bx2 + cx + d
and {1, x, x2, x3} are a linearly independent set spanning four-dimensional space.
Thus, it is an appropriate basis.
