1. The problem statement, all variables and given/known data Find the coordinates of α, β, and γ rel. to u, p, q (unit vectors) of x = 1/9( 2i + 62j - 11k )( (Note there orthogonal to each other) Question 2 : The position vectors of two points A, B has position vectors a = < 2, 1, 7> and b = <1, 4,-1> Find the parametric vector eq of the line AB using lambda as parameter. 2. Relevant equations For the first question I just did the dot product of x with each unit vector. I ended up with σ = 2 , β = 3 , γ = 6 What do you think? For the next question please don't give me an answer give me a question to direct my though if it is incorrect. Thanks. So I said x = a + λb Where b is a unit vector. Is this proper? I didn't want to expand it and write the vectors it will look a mess. I have the unit vector b = < 1/ (3sqrt 3), 4/ (3 sqrt 3), -1/ (3sqrt 3)> I think this is proper.
