Ex 10.2, 5 (Introduction) Find the scalar and vector components of the vector with initial point (2, 1) and terminal point (– 5, 7). Let vector π‘Žο·― = 2 𝑖﷯ – 5 𝑗﷯ + 4 π‘˜ο·― Then, Scalar components = 2, –5 and 4 Vector components = 2 𝑖﷯, –5 𝑗﷯ and 4 π‘˜ο·― Ex 10.2, 5 Find the scalar and vector components of the vector with initial point (2, 1) and terminal point (–5, 7). Let Initial point = A (2, 1) Terminal point = B (–5, 7) 𝐴𝐡﷯ = (βˆ’5 βˆ’ 2) 𝑖﷯ + (7 βˆ’ 1) 𝑗﷯ = –7 𝑖﷯ + 6 𝑗﷯ Scalar components = βˆ’7, 6 Vector components = βˆ’7 π’Šο·― , 6 𝒋﷯
