Ex 11.2, 4 Find the equation of the line which passes through the point (1, 2, 3) and is parallel to the vector 3 𝑖 + 2 𝑗 – 2 𝑘 . Equation of a line passing through a point with position vector 𝑎 , and parallel to a vector 𝑏 is 𝑟 = 𝑎 + 𝜆 𝑏 Since line passes through (1, 2, 3) 𝑎 = 1 𝑖 + 2 𝑗 + 3 𝑘 Since line is parallel to 3 𝑖 + 2 𝑗 − 2 𝑘 𝑏 = 3 𝑖 + 2 𝑗 − 2 𝑘 Equation of line 𝑟 = 𝑎 + 𝜆 𝑏 𝒓 = ( 𝒊 + 2 𝒋 + 3 𝒌) + 𝜆 (3 𝒊 + 2 𝒋 − 2 𝒌)
