Let x=(x₁,x₂,…,xₙ) and y=(y₁,y₂,…,yₙ) be two vectors in ℜⁿ. Define, x⊗ y=Σᵢ₌₁ⁿxᵢ|yᵢ|, where |yᵢ| stands for absolute value. How many of the following statements are correct: Statement 1: x⊗ y=y⊗ x. Statement 2: x⊗ x=0 implies x=(0,0,…,0). Statement 3: x⊗(c.y)=c(x⊗ y), where c∈ℜ₊₊ and c.y=(cy₁,cy₂,…,cyₙ) (A) 0 (B) 1 (C) 2 (D) 3
Also written as: Let x=(x_1,x_2,...,x_n) and y=(y_1,y_2,...,y_n) be two vectors in Re^n. Define, x(x) y= sum_(i=1)^nx_i|y_i|, where |y_i| stands for absolute value. How many of the following statements are correct: Statement 1: x(x) y=y(x) x. Statement 2: x(x) x=0 implies x=(0,0,...,0). Statement 3: x(x)(c.y)=c(x(x) y), where c in Re_(++) and c.y=(cy_1,cy_2,...,cy_n)
