CHAP03 Vectors and Matrices in 3 Dimensions
... We defined the determinant of a 2 × 2 matrix as the signed area of a certain parallelogram. We shall define the determinant of a 3 × 3 matrix as the signed volume of a certain parallelepiped. Of course these definitions can only work if the components of the matrices are real numbers. In a later cha ...

... b) Assume that F has the property that 1 + 1 6= 0. Let f (x) ∈ V be a nonzero function such that f (−c) = f (c) for all c ∈ F , and let g(x) ∈ V be a nonzero function such that g(−c) = −g(c) for all c ∈ F . Prove that { f (x), g(x) } is linearly independent. 9. Suppose that x, y and z are distinct v ...

VECTOR ANALYSIS
... A scalar is a quantity that has only magnitude. Quantities such as time, mass, distance, temperature, entropy, electric potential, and population are scalars. A vector is a quantity that has both magnitude and direction. Vector quantities include velocity, force, displacement, and electric field int ...

Lecture 1 Linear Superalgebra
... We may say that this is the point where linear supergeometry differs most dramatically from the ordinary theory. Proposition 5.3. Let T : Ap|q −→ Ap|q be a morphism with the usual block form (2). Then T is invertible if and only if T1 and T4 are invertible. Proof. Let JA ⊂ A be the ideal generated b ...
