As shown on Figure 1, the dual basis vectors are perpendicular to all basis vectors with a di erent index, and the scalar product of the dual basis vector with the basis vector of the same index is unity.

www.ms.uky.eduLet V and W be vector spaces over the real numbers. Suppose that T is a function from V to W, T:V 6 W. T is linear (or a linear transformation) provided that T preserves vector addition and scalar multiplication, i.e. for all vectors u and v in V, T(u + v) = T(u) + T(v) and for any scalar c we have T(cv) = cT(v).
