Ex 10.2, 7 Find the unit vector in the direction of the vector π β = π Μ + π Μ + 2π Μ π β = π Μ + π Μ + 2π Μ, = 1π Μ + 1π Μ + 2π Μ, Magnitude of π β = β(12+12+22) |π β | = β(1+1+4) = β6 Unit vector in direction of π β = π/|π β | . π β π Μ = 1/β6 ["1" π Μ" + 1" π Μ" + 2" π Μ ] π Μ = π/βπ π Μ + π/βπ π Μ + π/βπ π Μ
