Effortless Linear Algebra develops and explains in cautious element the computational options and basic theoretical effects valuable to a primary path in linear algebra. This hugely acclaimed textual content makes a speciality of constructing the summary pondering crucial for extra mathematical learn. The authors supply early, in depth realization to the abilities essential to make scholars ok with mathematical proofs. The textual content builds a steady and soft transition from computational effects to normal idea of summary vector areas. It additionally offers flexbile assurance of useful functions, exploring a accomplished variety of themes.

18. Using trigonometry, we see that when 0 Յ Յ 2 , the vector p has length b cos and is in the direction of the unit vector a/ a . Also, when 2 < Յ , p has length Ϫ b cos and is in the direction of the unit vector Ϫa/ a . 18 The projection p of b onto a (when is obtuse) a . 2 The Dot Product 25 But we know that cos ϭ (a · b)/( a b ), and hence pϭ a·b a. a 2 The projection p of vector b onto a is often denoted by proja b. Example 6 Let a ϭ [4, 0, Ϫ3] and b ϭ [3, 1, Ϫ7]. Then proja b ϭ p ϭ ϭ (4)(3) ϩ (0)(1) ϩ (Ϫ3)(Ϫ7) a·b 33 aϭ a aϭ 2 2 √ 25 a 16 ϩ 0 ϩ 9 132 99 33 [4, 0, Ϫ3] ϭ , 0, Ϫ .
Proof. 2 is certainly in the same direction as x because u is a positive scalar multiple of x (the scalar is 1/ x ). 1, u ϭ (1/ x )x ϭ (1/ x ) x ϭ 1, so u is a unit vector. 6). 6 Normalizing a vector x to obtain a unit vector u in the same direction (with x > 1) Example 2 √ Consider the vector [2, 3, Ϫ1, 1] in R4 . Because [2, 3, Ϫ1, 1] ϭ 15, normalizing [2, 3, Ϫ1, 1] gives a unit vector u in the same direction as [2, 3, Ϫ1, 1], which is uϭ 1 2 3 Ϫ1 1 [2, 3, Ϫ1, 1] ϭ √ , √ , √ , √ . √ 15 15 15 15 15 8 CHAPTER 1 Vectors and Matrices Addition and Subtraction with Vectors aa Deﬁnition Let x ϭ [x1 , x2 , .
