1.5 draw the following vector
1.2 What is a vector? (Section 2.2) Two properties (attributes) of a vector are magnitude and direction 1.3 What is a zero vector? (Section 2.3) A zero vector 0 has a magnitude of 0/1/2/o. A zero vector 0 has no direction. True/False. 1.4 Unit vectors. (Section 2.4) A unit vector has a magnitude of 0/1/2/oo. All unit vectors are equal. True/False. 1.5 Draw the following vectors: (Section 2.2) Long, horizontally-right vector ã • Short, vertically-upward vector b Outwardly-directed unit vector ĉ 1.6 & Vector magnitude and direction (orientation and sense). (Section 2.2) The figure to the right shows a vector v. Draw the following vectors. • a: Same magnitude and same direction as v (a = v). • b: Same magnitude and orientation as v, but different sense. • č: Same direction as v, but different magnitude. • d: Same magnitude as v, but different direction (orientation). • ē: Different magnitude and different direction (orientation) as v. 1.7 4 Magnitude of a vector. (Section 2.2) Consider a real number x and a horizontally-right pointing unit vector i. The magnitude of the vector -xi is (circle one): positive negative non-negative non-positive. 1.8 4 Negating a vector. (Section 2.8) Complete the figure to the right by drawing the vector -b. Negating the vector b results in a vector with different (circle all that apply): (direction orientation sense magnitude Historical note: Negative numbers (e.g., -3) were not widely accepted until 1800 A.D. 57 Homework 1: Vectors basis independent opyright © 1992-2017 Paul Mitiguy.
