Web〈1, 2, 1〉 × v = 〈3, 1, –5〉 (b) Explain why there is no vector v such that 〈1, 2, 1〉 × v = 〈3, 1, 5〉 Step-by-step solution 100% (6 ratings) for this solution Step 1 of 4 (a) The objective is … WebLet v = ( − 1, 0, 2) and u = ( 3, 1, − 2) so we need to find x = ( x 1, x 2, x 3) such that v ⋅ x = 0 and u ⋅ x = 0. This gives us the set of linear equations − x 1 + 2 x 3 = 0 3 x 1 + x 2 − 2 x 3 = 0 which, through elementary row operations gets us the two linear equations x 1 − 2 x 3 = 0 x 2 + 4 x 3 = 0

linear algebra - Finding a vector $v_3$ such that $\{v_1, v_2, v_3 ...
Web3. (a) Explain why there is no vector i such that (3, –1, 4) × J = (-5,1, –4). (b) Explain why there are infinitely many vectors i such that (3, –1, 4) × i = (-5, 1,4), then find all such vectors by expressing the components of all such vectors i in terms of a single variable. WebUse vectors to decide whether the triangle with vertices P (1, -3, -2), Q (2, 0, -4), and R (6,-2, -5) is right-angled. calculus Let C be the point on the line segment AB that is twice as far from B as it is from A. If a= ^→OA, b=^→OB, and c=^→OC, show that c … WebSo you have to find a vector v such that grad f, v = 0 Thus, in your case: − 2 v x − 2 v y = 0 This is satisfied by all vectors of the form v = ( t, − t) ⊤ with t ∈ R. So a corresponding unit vector is e.g. u = ( 1 2, − 1 2) ⊤, because ‖ u ‖ = 1. Share Cite Follow edited Jan 18, 2016 at 9:04 answered Jan 17, 2016 at 20:16 adjan 5,661 17 38 exoterbyn árgép
