The Answer of Let a = $\langle - 2,3,1 \rangle$ and b = $\langle 6 , c , - 3 \rangle$ .(a) Find the value of c such that a and b are orthogonal.(b) Find the value of c such that a and b are parallel.

Let a = ⟨−2,3,1⟩\langle - 2,3,1 \rangle⟨−2,3,1⟩ And B = ⟨6,c,−3⟩\langle 6 , c , - 3 \rangle⟨6,c,−3⟩

Let a = $\langle - 2,3,1 \rangle$ And B = $\langle 6 , c , - 3 \rangle$
