Web31 okt. 2024 · Definition 11.1.1 THe Position Vector. Let P = (p1, ⋯, pn) be the coordinates of a point in Rn. Then the vector → 0P with its tail at 0 = (0, ⋯, 0) and its tip at P is called the position vector of the point P. We write → 0P = [p1 ⋮ pn] For this reason we may write both P = (p1, ⋯, pn) ∈ Rn and → 0P = [p1⋯pn]T ∈ Rn. Web16 sep. 2024 · Now suppose n = 2.

Web16 sep. 2024 · This is a very important notion, and we give it its own name of linear independence. A set of non-zero vectors {→u1, ⋯, →uk} in Rn is said to be linearly independent if whenever k ∑ i = 1ai→ui = →0 it follows that each ai = 0. Note also that we require all vectors to be non-zero to form a linearly independent set. WebTwo vectors x, y in R n are orthogonal or perpendicular if x · y = 0. Notation: x ⊥ y means x · y = 0. Since 0 · x = 0 for any vector x, the zero vector is orthogonal to every vector in R n. We motivate the above definition using the law of cosines in R 2.
