PassageConsider u1=(13,−13,13)u_1=\left(\frac1{\sqrt3},-\frac1{\sqrt3},\frac1{\sqrt3}\right), u2=(12,0,−12)u_2=\left(\frac1{\sqrt2},0,-\frac1{\sqrt2}\right), and u3=(16,2k6,k6)u_3=\left(\frac1{\sqrt6},\frac{2k}{\sqrt6},\frac{k}{\sqrt6}\right) in R3\mathbb{R}^3, where k∈Rk\in\mathbb{R}. Use the standard inner product to answer the subquestions.
QuestionFind the value of kk for which {u1,u2,u3}\{u_1,u_2,u_3\} is an orthonormal basis of R3\mathbb{R}^3.
