Unformatted text preview: ECE 493 HW #3 – Version 1.00 March 11, 2011 Spring 2011 Univ. of Illinois Due Thur, Mar. 17 Prof. Allen Topic of this homework: RanknSpan; Taylor series; Vector fields, Gradient Vector field topics Deliverables: Show your work. Numerical results are not sufficient, expect when specifically requested. General definitions: ˆ i , ˆ j , ˆ k are given in Greenberg on page 689: ˆ i · ˆ i = ˆ j · ˆ j = ˆ k · ˆ k = 1 , ˆ i · ˆ j = ˆ j · ˆ k = ˆ i · ˆ k = 0 , (1) ˆ i × ˆ i = 0 , ˆ i × ˆ j = ˆ k , ˆ k × ˆ j = ˆ i , ··· . (2) 1. Triple product: Let→ A = [ a 1 ,a 2 ,a 3 ] T ,→ B = [ b 1 ,b 2 ,b 3 ] T ,→ C = [ c 1 ,c 2 ,c 3 ] T be three vectors in R 3 .
