Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
1. Let V₁, V2,...,Vn be n vectors in a vector space V. Explain what it means to say that these
vectors span V.
3. Let V = C2 and F = C along with the following operations defined:
(a1,a2) + (b1, b2) =(a1 + b1 + 1, az + b2 + 1)
C(a1, a2) =(ca1 + c – 1, ca2 + c – 1)
Determine whether this is a Vector Space.
In any vector space V, show that (a + b)(x + y) = ax + ay + bx + by for
any x, y e V and any a, be F.
